Hinduism, Buddhism and Jainism derived from the Upanishads

Isha Upanishad

By the Master all this is to be clothed and pervaded, whatever moves in this moving world. Through this renounced, thou shalt enjoy; covet not the wealth of any! Toiling, therefore, here at his tasks, let him be willing to live a hundred ages; this is it with thee, and not otherwise, nor does work smear and befoul the man. Sunless, verily, are those worlds, by blind darkness enwrapped; they enter into those worlds on going forth—the men who are slayers of their own souls. Without moving, that One is swifter than mind. Nor did the bright Powers overtake It; It went swiftly before them. That outstrips the others, though they run, while It stands still. In That Matarishvan disposes the life-streams. That moves, That moves not; That is afar off, That is as if near. That is within all this; That is outside all this. But he who beholds all beings in the supreme Self (Atma), and in all beings beholds the supreme Self, does not seek to hide himself from That. In whom all beings have become as the Self of the enlightened, what delusion is there, what sorrow, for him beholding Oneness?

The Isha Upanishad is one of the shortest of the ancient Sanskrit scriptures known as the Upanishads, meaning “sitting down near” – the manner by which the student learned from the master. Hinduism, Buddhism and Jainism all derive to a greater or lesser extent their principles of belief from the Upanishads. Considered on a par with the Beatitudes of the Christian scriptures for its terse exposition of the ways and means to blessedness, the Isha Upanishad is often honored by being placed first in any collection of Upanishads, although its actual dating in reference to the other Upanishads (mostly composed sometime in the first millennium BC) is hotly contested among Eastern scholars.
