3. Foundations of Yoga
Self-control — Purification of Nature — Peace and Surrender
This state of sleep is very good. Sleep must be conscious like this.
It happens like this when sleep becomes conscious — the sadhana continues in sleep as in waking.
The rule in this sadhana is to bring down everything, to have all the spiritual experiences in the waking state. Of course, in the early stages there is more meditation and it may be very beneficial right to the end — but, if the experiences are obtained in meditation only, the entire being is not transformed. For this reason to have them in a waking state is a good sign.
