Siddharta had a goal, a single one: to become empty – empty of thirst, empty of desire, empty of dreams, empty of joy and sorrow.

To die away from himself, no longer be self, to find peace with an emptied heart, to be open to miracles in unselfed thinking: this was his goal.

When the entire self was transcended and extinct, when every drive and every mania in the heart had fallen silent, then the ultimate was bound to awaken, the innermost essence, which is no longer ego, the great secret.

'Siddhartha' by Nobel laureate Hermann Hesse
