This comment on Persinger's paper published in this journal in 1994 includes 4 studies not cited by Persinger. Each supports the inference of better health of those who practice Transcendental Meditation.
Eighty-three black college students, staff and adults were pretested on EEG coherence, skin potential (SP) habituation to a series of loud tones, psychometric measures of mental health (Tennessee Self-Concept Empirical Scales and Spielberger State-Trait Anxiety Inventory) and IQ. They were then randomly assigned to one of the three treatment groups: the Transcendental Meditation technique (TM); Progressive Muscle Relaxation (PR); or cognitive-behavioral strategies (C). Approximately one year later, they were posttested. TM and PR increased significantly on an overall mental health factor (p less than .036) and anxiety (p less than .0006). TM showed a greater reduction in neuroticism than PR and C (p less than .032). TM also showed global increases in alpha and theta coherence among frontal and central leads during the TM period compared to eyes closed (p less than .016), whereas PR and C did not show EEG state changes. The coherence increases during TM were most marked in the right hemisphere (F4C4). TM showed faster SP habituation at posttest compared to pretest (p less than .047) whereas PR did not (data was missing for C). None of the groups showed longitudinal changes in EEG, perhaps due to lack of regularity of participation in the treatment programs.
EEG coherence was measured between pairs of three different subjects during a one-hour period practice of the Transcendental Meditation (TM) program. Coherence between subjects was evaluated for two sequential fifteen minute periods. On six experimental days, these periods preceded and then coincided with a fifteen minute period during which 2500 students participated in the TM-Sidhi program at a course over 1000 miles away. After the course had ended coherence was evaluated on six control days. It was found that intersubject coherence was generally low, between 0.35 and 0.4, with coherence in the alpha (8-12 Hz) and beta (16-20 Hz) frequencies significantly higher than at other frequencies. On the experimental days, intersubject EEG coherence increased during the experimental period relative to the fifteen minute baseline period immediately preceding the experimental period. Coherence increased significantly from baseline to experimental periods on experimental days compared with control days (p = 0.02). This effect was particularly evident in the alpha and beta frequencies. The results reinforce previous sociological studies showing decreased social disorder in the vicinity of TM and TM-Sidhi participants and are discussed in terms of a field theoretic view of consciousness.
In a study designed to identify the electrophysiologic characteristics of the Transcendental Meditation Program, 52 periods of spontaneous respiratory suspension (RS) were observed in 18 subjects during the practice of this program. These periods were correlated with some but not all the subjective experiences of pure consciousness. Nineteen RS periods (belonging to 11 subjects) free from any artifact were selected for EEG analysis. The mean total EEG coherence over all frequencies and over nine derivations for TM subjects showed a significant increase during the RS periods as compared to pre- and post-RS control periods. There was no significant change in mean total EEG coherence in a control group of 30 subjects voluntarily holding their breath. The heart rate showed a significant decrease during the RS periods in both the experimental and control groups, whereas there was no significant change in EEG alpha power in either group. These findings extend those of previous studies and help characterize the physiologic correlates of the state of pure consciousness during the TM program.
This field study compared 5 years of medical insurance utilization statistics of approximately 2000 regular participants in the Transcendental Meditation (TM) program with a normative data base of approximately 600,000 members of the same insurance carrier. The benefits, deductible, coinsurance terms, and distribution by gender of the TM group were very similar to the norm, yet the TM group had lower medical utilization rates in all categories. Inpatient days per 1000 by age category were 50.2% fewer than the norm for children (0-18), 50.1% fewer for young adults (19-39), and 69.4% fewer for older adults (40+). Outpatient visits per 1000 for the same age categories were, respectively, 46.8%, 54.7%, and 73.7% fewer. When compared with five other health insurance groups of similar size and professional membership, the TM group had 53.3% fewer inpatient admissions per 1000 and 44.4% fewer outpatient visits per 1000. Admissions per 1000 were lower for the TM group than the norm for all of 17 major medical treatment categories, including -55.4% for benign and malignant tumors -87.3% for heart disease, -30.4% for all infectious diseases, -30.6% for all mental disorders, and -87.3% for diseases of the nervous system. However, the TM group's admission rates for childbirth were similar to the norm. The issue of self-selection is addressed in terms of previous medical research in this area.
