The senses of the wise man obey his mind, his mind obeys his intellect, his intellect obeys his ego, and his ego obeys the Self.
Arise! Awake! Approach the feet of the Master and know THAT. Like the sharp edge of a razor, the sages say, is the path. Narrow it is, and difficult to tread !
Soundless, formless, intangible, undying, tasteless, less, odorless, eternal, without beginning, without end, immutable, beyond nature, is the Self. Knowing ing him as such, one is freed from death.
