The Hindu scriptures, like the Buddhist, dwell ... on withdrawal from the realm of pleasure. The spiritually mature man is one who "abandons desires," who "has lost desires for joys," who "withdraws, as a tortoise his limbs from all sides, his senses from the objects of sense." Hence the ideal man as depicted in the Bhagavad Gita: a man of discipline, who acts without worrying about the fruits of his action, a man who is unmoved by acclaim and by criticism.... That Hinduism and Buddhism sound so much alike is not shocking. The Buddha was born a Hindu. But he carried the theme of sensory indifference further, boiling it down to a severe maxim—life is suffering—and placing it in the center of his philosophy.
