When Brahman woke, Vishnu sprung forth from the belly button of Brahma - as a newborn is tied by the belly button to its mother, Brahma and Vishnu were bound. There was existence everywhere, and Vishnu, out of the purest love and joy, because of the nature of things, delighted to play in it. This was how the universe was made for Brahma to discover.
The world fell in love with Vishnu! But when at last Vishnu's play took him to a place hidden from the world, the world, like a woman bereft of her love, wondered how she might sustain herself against such unrequited love? The world sought the great Muni Kasyapa for guidance. The Muni suggested she seek her love, Vishnu and lay bare her heart. The search brought the world far, but at last Vishnu was found: the world laid bare her heart to Vishnu.
Vishnu comforted her, "love those who practice their duties and act to uphold the Dharma as Me; they will sustain you." With the world seated at ease in his company, Vishnu proclaimed many duties: to teach by sacrifice, to practice by protection, to care for and tender by commerce and industry, to serve through the arts. Forbearance, veracity, restraint, purity, liberality, self-control, harmlessness, obedience, pilgrimaging, compassion, straightforwardness, contentment, reverence, equanimity. "These will sustain your heart."
