Devas or Asuras, will follow this doctrine (upanishad), will perish.'
II. In the Khând. Up. I, 1, after the deeper meaning of the Udgîtha or Om has been described, the advantage of knowing that deeper meaning is put forward, and it is said that the sacrifice which a man performs with knowledge, with faith, and with the Upanishad, i. e. with an understanding of its deeper meaning, is more powerful.
III. In the Taittirîya-upanishad, at the end of the second chapter, called the Brahmânandavallî, and again at the end of the tenth chapter, the text itself says: Ity upanishad, 'this is the Upanishad, the true doctrine.'
IV. In the Kaushîtaki-upanishad II, 1; 2, we read: 'Let him not beg, this is the Upanishad for him who knows this.' Here upanishad stands for vrata or rahasya-vrata, rule.
