The Philosophy of the Upanishads c5.s3.45

c5.s3.45

If the passages collected in my index to the Upanishads under the word Upanishad are examined, it will be at once evident that, taken together, they involve the meaning, “secret sign, secret name, secret import, secret word, secret formula, secret instruction,” and that therefore to all the meanings the note of secrecy is attached. Hence we may conclude that the explanation offered by the Indians of the word *upanishad* as *rahasyam*, “secret,” is correct.
