Upanishads are the ancient scriptures of India. They are mainly a dialogue between the student and the teacher on life, spirituality, and answers to the questions that the student has on who is the maker of this world, why is there suffering and happiness, what happens after death, how will we know our Creator, etc.?
The Upanishads do not consider God as a separate entity, but as a part of our own being. They do not mention any rituals to be followed. They state that each one of us is responsible for our own sadness and happiness, and by looking inwards we will know ourselves and then know that everybody has the same element as us - the spirit or atma.
In this episode two Upanishads have been explained: Ishavasya Upanishad and Kaevallya Upanishad.
Malti Johari, in the early 1990,s, tanslated 10 Upanishads in verse form. The book is available on her website. The podcast is an abridged version of the Upanishads.
