One month Gayatri Yagya (with specific herbal preparations) experiments were recently carried out at Brahmavarchas research center upon about 30 to 40 males and equivalent numbers of females suffering from Anxiety/Depression/Guilt/Insomnia. The control groups consisted of about ten subjects in each category.
The statistical analysis of results (on psychological tests for measure of the extent of above diseases/disorders) showed significant improvement in the experimental group.
Some Ph. D. projects (in the Dev Sanskrati University of Shantikunj, Hardwar) are currently on going on further studies in this regard.
