== Analysis Goals ==
 +
 +
The Kundalini Profile Survey was created to document the types of spiritual experiences people are having, and associated physical and psychological experiences.
 +
 +
Analysis on the Kundalini Profile Survey has a few basic goals:
 +
 +
* Discover groupings of Kundalini experiences that occur together.
 +
* Explore the relationship between different experience types and other physical and psychological experiences.
 +
* Create an empirical, data-driven way of classifying a person's spiritual experiences.
 +
* Lay the groundwork for future experimentation on Kundalini by providing important measures that can be used to track progress. Future research will focus on potential ways to enhance or accelerate the Kundalini process. Kundalini is seen as the biological basis of all spiritual experiences.

=== Variable Cluster Analysis ===
+
Factor analysis was conducted on the 66 primary experience questions. Factor analysis is a technique of identifying groups of correlated variables that correspond to latent categories of experiences. The mystical, spiritual, and psychophysiological question categories were analyzed. The number of factors to be determined per category was determined using an empirical technique known as parallel analysis. Principal Axis Factoring with Promax rotation was performed, a technique commonly used for this type of psychological data.
−
=== Composite Variables ===
+
 
 +
One key observation during this process was the prominence of a single factor, labeled "Higher Consciousness," which accounted for a very large portion of explained variance in the data. To illustrate this point, all 66 questions were used in the following scree plot, in which Higher Consciousness is shown as the first factor:
 +
 
 +
[[File:Mystical-spiritual-psyphys-parallel-scree.png|center|Scree plot showing an extremely eigenvalue for high Higher Consciousness]]
 +
 
 +
According to the Kundalini Hypothesis, Higher Consciousness is the goal of the Kundalini biological mechanism, and all other manifestations of Kundalini are secondary effects. In our analysis, Higher Consciousness was characterized by:
 +
 
 +
# The direct perception of consciousness.
 +
# Unity and the personal identification with all of creation
 +
 
 +
Factor analysis yielded the resulting factors in each major experience category. The questions listed below have a factor loading > ~0.6. This threshold was selected for interpretability of the data:

 +
The '''M-Class''' ('''mclass''') or "mystical classification" is a way to classify survey participants into distinct groups. The purpose of the M-Class model is to understand the differences between distinct types of Kundalini experiences and to develop methods to awaken Kundalini and reach Higher Consciousness.
 +
 
 +
The M-Class model uses Latent Class Analysis (LCA), a special type of mixture model developed for polytomous data. Other forms of cluster analysis such as K-means are based on arbitrary Euclidean distances, whereas latent class analysis is probabilistic and based on maximum likelihood estimates, and is thus a more empirical approach to clustering.
 +
 
 +
From the factor analysis (see above), key variables were identified and used in the M-Class model to classify respondents into different groups. The variables used are listed below:

Based on this model specification, two classes of experiencers were identified using the lowest Bayesian information criterion (BIC) out of a trial of 2-10 classes. The two distinct groups of experiencers are:
 +
 
 +
* '''Class 1 ("Kundalini stirring or Kundalini inactive")''' - These individuals were either symptomatic, or had very few symptoms of a Kundalini awakening. The group comprised 49% of respondents.
 +
* '''Class 2 ("Kundalini active")''' - Kundalini active respondents. These individuals generally had strong indications of Higher Consciousness (probably at least one peak experience). Out of Body and Light sensations occurred less frequently, but still more often than in the Class 1 group. The group comprised a 51% of respondents, which is representative only of the people filling out the survey, rather than the general population. The percentage of people with these types of experiences within the general population is unknown and would be a desirable data point.

 +
A decision tree analysis was run on psychological indicators (<code>psygrowth</code> and <code>psybliss</code>). The question answered is "what are the major psychological differences between Class 1 and Class 2 groups (limited by the types of questions asked)?" Analysis of the decision tree revealed three variables that appear related to the psychological profile of both groups of participants. Class 2 was more likely to indicate the following as psychological attributes:
 +
 
 +
* '''Devotional focus''' (<code>psybliss13</code>)
 +
* '''An interest in helping others, compassion for the suffering''' (<code>psygrowth10</code>)
 +
* '''Deep compassion''' (<code>psygrowth30</code>)
 +
 
 +
The pattern of experience is clear - a more devotional, compassionate frame of mind appears to play an important role in the Kundalini process. The decision trees used in this analysis are included below, with the variables above highlighted in red.

The Kundalini Profile Survey is part of the Emerging Sciences Foundation's Kundalini Experimental Project hosted on the Brilliano collaboration tool. The survey contains 268 five-point likert scale questions, open text fields, and questions about the impact of a person's spiritual experiences. The analysis documented on this page is being conducted by the Emerging Sciences Foundation's Kundalini Data Insights team. The complete source code for all analysis presented here can be found on the Kundalini Discover project in GitHub.

Analysis Goals

The Kundalini Profile Survey was created to document the types of spiritual experiences people are having, and associated physical and psychological experiences.

Analysis on the Kundalini Profile Survey has a few basic goals:

  • Discover groupings of Kundalini experiences that occur together.
  • Explore the relationship between different experience types and other physical and psychological experiences.
  • Create an empirical, data-driven way of classifying a person's spiritual experiences.
  • Lay the groundwork for future experimentation on Kundalini by providing important measures that can be used to track progress. Future research will focus on potential ways to enhance or accelerate the Kundalini process. Kundalini is seen as the biological basis of all spiritual experiences.

Summary Information

To date, 449 people from all walks of life and from across the globe have participated in the Kundalini Profile Survey.

Age and Sex

There has been broadly an equal participation from men and women, although there were slightly more women who took part. People of all ages have taken part in the survey with the majority of respondants being around the age of 30.

Age of Survey Participants

Core Experience Summary

The survey contains a list of 66 "core experience" questions describing classical Kundalini awakening indicators. The list was derived from previous surveys and existing literature, and respondents reported the strength of their experiences along a 5-point likert scale.

The survey contains three categories of experiences:

  1. Mystical indicators are those that typically transcend the normal bounds of human experience.
  2. Spiritual indicators are those that, although they may have sublime characteristics, might not be as radical as mystical experiences.
  3. Psychophysiological indicators are those that affect the body and mind through some not yet understood connecting medium.

In the data, these are represented as the mystical, spiritual, and psyphys (psychophysiolocical) question categories. In general, the data shows a very common occurrence of powerful, transformative experiences among respondents. Prevalent experiences in each category include:

  • Mystical experiencies associated with the perception of unity and consciousness.
  • Spiritual indicators associated with wisdom and intuition.
  • Psychophysiolocal experiences associated with energy vibrating or moving in the body.

Primary Experience Categories Factor Analysis

Factor analysis was conducted on the 66 primary experience questions. Factor analysis is a technique of identifying groups of correlated variables that correspond to latent categories of experiences. The mystical, spiritual, and psychophysiological question categories were analyzed. The number of factors to be determined per category was determined using an empirical technique known as parallel analysis. Principal Axis Factoring with Promax rotation was performed, a technique commonly used for this type of psychological data.

One key observation during this process was the prominence of a single factor, labeled "Higher Consciousness," which accounted for a very large portion of explained variance in the data. To illustrate this point, all 66 questions were used in the following scree plot, in which Higher Consciousness is shown as the first factor:

According to the Kundalini Hypothesis, Higher Consciousness is the goal of the Kundalini biological mechanism, and all other manifestations of Kundalini are secondary effects. In our analysis, Higher Consciousness was characterized by:

  1. The direct perception of consciousness.
  2. Unity and the personal identification with all of creation

Factor analysis yielded the resulting factors in each major experience category. The questions listed below have a factor loading > ~0.6. This threshold was selected for interpretability of the data:

The Mystical Classification (M-Class) Model

The M-Class (mclass) or "mystical classification" is a way to classify survey participants into distinct groups. The purpose of the M-Class model is to understand the differences between distinct types of Kundalini experiences and to develop methods to awaken Kundalini and reach Higher Consciousness.

The M-Class model uses Latent Class Analysis (LCA), a special type of mixture model developed for polytomous data. Other forms of cluster analysis such as K-means are based on arbitrary Euclidean distances, whereas latent class analysis is probabilistic and based on maximum likelihood estimates, and is thus a more empirical approach to clustering.

From the factor analysis (see above), key variables were identified and used in the M-Class model to classify respondents into different groups. The variables used are listed below:

M-Class Model Variables

Variable Name Likert Question Text Experience Type (from factor analysis) Used as predictor variable? Used as an indicator variable?
mystical4 Intense feeling of peace Ecstacy Yes
mystical5 Overwhelming sense of love Ecstacy Yes
mystical13 All sense of separateness disappears Union Yes
mystical22 Expansion of consciousness Consciousness Yes
mystical24 Experience of Higher consciousness/cosmic consciousness Consciousness Yes
mystical26 Personal identification with all of creation Union Yes
spiritual1 Spiritual rebirth - spontaneous religious conversion or dramatic spiritual awakening, including a major reorientation of spiritual beliefs. Rebirth Yes
spiritual2 New understanding of spiritual truths/Insight into the inner meaning of spiritual teachings Rebirth Yes
spiritual14 Out of body experiences OOB Yes
spiritual15 Astral/time travel experiences OOB Yes
spiritual17 Receiving inner instruction Intuition Yes
spiritual20 Feeling of connection with a spiritual guide or lineage Intuition Yes
psyphys3 Sensations of energy rushing up the spine Energy Yes
psyphys5 Feelings of energy flowing or vibrating within Energy Yes
psyphys11 Visions of light Light Yes
psyphys12 Floating in the light Light Yes


Based on this model specification, two classes of experiencers were identified using the lowest Bayesian information criterion (BIC) out of a trial of 2-10 classes. The two distinct groups of experiencers are:

  • Class 1 ("Kundalini stirring or Kundalini inactive") - These individuals were either symptomatic, or had very few symptoms of a Kundalini awakening. The group comprised 49% of respondents.
  • Class 2 ("Kundalini active") - Kundalini active respondents. These individuals generally had strong indications of Higher Consciousness (probably at least one peak experience). Out of Body and Light sensations occurred less frequently, but still more often than in the Class 1 group. The group comprised a 51% of respondents, which is representative only of the people filling out the survey, rather than the general population. The percentage of people with these types of experiences within the general population is unknown and would be a desirable data point.

The M-Class is not a static model, but one that will be refined based on multiple criteria, including confirmatory analysis, interpretability, and experimental value.

M-Class Profiles

This research assumes that people falling under different M-Class's will have different characteristics, behaviors, etc. Profiling means to examine each M-Class group and determine what these attributes are. Profiling of the M-Class model was first conducted using decision trees. Decision trees are a machine learning algorithm which looks at an outcome variable, in this case the mclass variable, and determines the best way to predict that outcome (or set of outcomes) based on the values of a number of predictor variables. The output is provided in the form of a tree plot. More information about how to interpret the tree plots used in our analysis can be found here (external PDF).

Psychological Differences

A decision tree analysis was run on psychological indicators (psygrowth and psybliss). The question answered is "what are the major psychological differences between Class 1 and Class 2 groups (limited by the types of questions asked)?" Analysis of the decision tree revealed three variables that appear related to the psychological profile of both groups of participants. Class 2 was more likely to indicate the following as psychological attributes:

  • Devotional focus (psybliss13)
  • An interest in helping others, compassion for the suffering (psygrowth10)
  • Deep compassion (psygrowth30)

The pattern of experience is clear - a more devotional, compassionate frame of mind appears to play an important role in the Kundalini process. The decision trees used in this analysis are included below, with the variables above highlighted in red.
