This is a cassette tape of the Rigveda that I purchased from Maharishi Institute of Management! It is said that listening to it for 20 minutes after meditation will solidify the state achieved. I put it away after listening to it several times, and although years have passed and the case has some minor stains, the tape itself is clean and the sound quality is very good. #MaharishiInstituteOfManagement #Rigveda
