The Isavasyopanishad emphasises the need for balance. In verses which are
unfortunately obscure (9, 11, 12, and 14), the importance of both know ledge and
discipline, and of attention to matter as well as to spirit is dealt with.
The Upanishad winds up with a prayer for
strength to maintain internal and external purity.
Addressing the morning sun, the aspirant is
taught to feel and say, "O Sun, of refulgent glory, I am the same person as He that
is in you." And he is asked to say to himself: "My body will disintegrate but
not I and my deeds. O Mind, remember this always, remember this always."
