“Vedic Astrology” course added in Indian University courses and decided that “There is an urgent need to rejuvenate the science of Vedic Astrology in India, to allow this scientific knowledge to reach to the society at large, and to provide opportunities to get this important science even exported to the world, the University Grants Commission decided to approve ‘in principle’ setting up of few departments of ‘Vedic Astrology’ in Indian universities.
This would provide a exclusive teaching and training in the subject leading to certificate, diploma, under-graduate, post-graduate and Ph.D. degrees”. The University Grants Commission approved the guidelines and decided that courses should be renamed as “JYOTIR VIGYAN”.
