Note 1 — Chapter CXXXXVIII · Investigation into the Nature of Dreams.
Viharilala Mitra translation
The mind involved in ignorance, is said to be waking, and the uncontrouled mind is styled as dreaming: the mind subdued by weariness is said to be asleep, and when brought under subjection by any effort, is called samádhi or meditation, lastly its liberation from ignorance, is known as its state of mukti or emancipation.
