Kaivalya Upanishad with Swami Viditatmananda
In this Upanishad, Rishi Asvalayana is taught the vision of non-duality, brahma-vidya, by Bhagavan himself through a unique method. The whole vision is initially communicated through instructions on contemplation, then reinforced using traditional methods of teaching. Some of the mantras are used in daily puja and for receiving a sadhu, and some contain portions of other Upanishads and the Bhagavad Gita. Kaivalya Upanishad is therefore a comprehensive introduction to the vision and a rich source for assimilating it.
