We chant at the beginning and end of each class so I've found a few recordings of the mantras we chant for you to listen to and learn, if you wish :)
Opening Chant - Sahana Vavatu
Closing Chant - Maha Mrityunjaya Mantra
The closing chant Asatoma Sadgamaya that we chant is part of the Maha Mrityunjaya mantra. The Maha Mrityunjaya mantra starts with the Tryambakam chant. Tryambakam is followed by the chants Sarvesham, Asatoma Sadgamaya and ends with Poornamadah - all of which can be heard below (excluding Tryambakam). We tend to only chant the Asatoma Sadgamaya part at the end of our classes.
