To keep yourself awake is not permissible – it depresses the body in the end and excites the brain and leads to an unquiet and unbalanced consciousness. The body needs sufficient rest in order to be able to bear the pressure of sadhana.Sri Aurobindo

To keep yourself awake is not permissible – it depresses the body in the end and excites the brain and leads to an unquiet and unbalanced consciousness. The body needs sufficient rest in order to be able to bear the pressure of sadhana.
You can pray or will before sleeping to be conscious in sleep, and you can get your waking mind full of the Mother. That is the best way. But you must not expect to be able to succeed all at once. First, the sleep-mind must become conscious of what it is doing in sleep; only afterwards can you determine what it is to do there.
