This is a very comprehensive longitudinal study over 10 years, taking in account mental abilities, emotional development, social development, and moral ethnical reasoning. Maharishi University of Management students who were practicing the Transcendental Meditation and TM-Sidhi programs, increased significantly in self-development (ego development) when measured after graduation (when starting in their professional lives), in contrast to control students from three other universities who were not participating in this program.
