“Put this salt in water and come to me in the morning.” In the morning: “Bring me the salt.” Śvetaketu looks and cannot find it, for it has dissolved. “Sip from this end — how is it?” “Salty.” “From the middle?” “Salty.” “From that end?” “Salty.” “Indeed, my dear, you do not perceive Being here — yet it is here. That which is the finest essence — this whole world has that as its Self. That is the Truth. That is the Self. That thou art, Śvetaketu.”
Other lessons in the sequence: the seed of the banyan split open — inside, nothing visible, yet from that “nothing” the great tree grows; rivers merging in the ocean, no longer saying “I am this river”; a blindfolded man left in a wilderness finding his way home with directions — as one with a teacher finds the way to the Self.
Arthur Schopenhauer took tat tvam asi as the metaphysical basis of compassion.
