There's all this consciousness talk, which I am the first person most guilty of in talking about consciousness. Chit Chaitanya does not mean consciousness in the sense we normally understand consciousness. It's also important to say once in a while, we are not consciousness. Let me read Vivekananda himself. What is God? Beyond speech, beyond thought, beyond consciousness. He says that could be quite surprising to somebody who's been studying Vivekananda. That means it does everything go away. No, pure consciousness remains.
Swami Sarvapriyananda teaches the Katha Upanishad, one of India's most revered texts which is also a part of the Vedas. It is a collection of philosophical poems representing a conversation between the sage Naciketas and Yama (god of death). They discuss the nature of Atman, Brahman and Moksha(liberation).
