Note 12 — Chapter CXVII · Different States of Knowledge and Ignorance.[12]

The Text uses the terms jnána and ajnána, which literally signify knowledge and ignorance, and mean to say that, we know the subjective ourselves only (as-ego-sum) and are ignorant of the true nature of the objective, as whether they are or not and what they are. Though it would be more appropriate to use the words nischaya and anischaya or certainty and uncertainty, because we are certain of our own existence, and are quite uncertain of every thing besides, which we perceive in our triple states of waking, dreaming and sound sleep, which incessantly produce and present before us a vast variety of objects, all of which lead us to error by their false appearances.
