Note 17 — THE UPANISHADS
Samuel Beal translation
Footnote 17:
(return)
Speech is uncertain, and has to be checked by the eye. The eye is uncertain, taking mother of pearl for silver, and must be checked by the ear. The ear is uncertain, and must be checked by the mind, for unless the mind is attentive, the ear hears not. The mind, lastly, depends on the spirit, for without spirit there is no mind.
