Chapter 6 JnAna and Moksha
6-5 Katha Upanishad
6-5-25 Katha 2.1.12 to 2.1.15 JivAtamA, i.e., embodied Self is as though situated in the heart of the body. It is Consciousness that illumines thoughtful and thoughtless states of the mind. The heart is of the size of the fist and the mind is imagined of the size of the thumb. The non-dual Self is the Lord of the past, present and the future. Although it appears to be limited in size, it is the limitless, all-pervading and is non-dual. The space within the pot is viewed as limited space. Upon inquiry, we understand that the expression limited space is a delusion. The space is neither inside nor outside the pot, but all pots are within the space. In the same way, Consciousness is neither within nor without the heart; everything is within consciousness. After knowing that I am the limitless consciousness, I never feel insecure. It is this Consciousness that Nachiketa has sought to know in the third boon.
