So the sensory system is external, gross, object compared to the mind which is subtle and internal. What do we do with this? We have to first understand what is being said and then notice it. Then like that you have to go.
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).
