Prithak bhava: Senses are separate. If you take a flower, the eyes will tell you one thing, that it's red. The nose will tell you another thing entirely. Every sense gives you different experiences. Then, and all of those experiences are revealed to you, to ourselves,. We experience it because of one thing in the background, this consciousness which you are, which I am, our real nature.
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).
