In the tastiest food given to me, I'm thinking of a yogi sitting in a cave. In any way, it is just giving upbursts. separating this righteous thing from the body, etc. and attaining this subtle thing that mortal rejoices. For he has obtained that which is the cause of delight. The mansion of Pranhmana is wide open to you, Nachiketa. Again, very nicely put, poetically. He says, Mater, O mortal man, O mortal being, yes, you are immortal,. but right now, the one who is seeking, is seeking only because we feel we are mortal. We are subject to birth
Swami Sarvapriyananda teaches the Katha Upanishad, which is one of India's most revered texts and 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).
