People's ideas of sound sleep are absolutely erroneous. What they call sound sleep is merely a plunge of the outer consciousness into a complete subconscience. They call that a dreamless sleep; but it is only a state in which the surface sleep consciousness which is a subtle prolongation of the outer still left active in sleep itself is unable to record the dreams and transmit them to the physical mind. As a matter of fact the whole sleep is full of dreams. It is only during the brief time in which one is in the Brahmaloka that the dreams cease.
When you are very tired and in need of rest and if you know how to exteriorise yourself, if you go out of your body and enter consciously into the vital world, there are regions there, in the vital world, which are like a marvellous virgin forest, with all the splendour of a rich and harmonious vegetation, and beautiful, mirror-like pools. And the atmosphere is filled with the living vitality of plants, with every shade of green reflected in the water... And there you feel so much life, so much beauty, so much richness and plenitude that you wake up full of energy. And all this is so objective! I have been able to take people there, without telling them anything at all about how it would be, and they were able to describe the place exactly as I can myself, and they had exactly the same experience. They were absolutely exhausted before going to sleep and they woke up with an absolutely marvellous feeling of plenitude, of force and energy. They had stayed there only for a few minutes.
If you go down into your lower parts or ranges of nature, you must be always
careful to keep a vigilant connection with the higher already regenerated levels of the consciousness and to bring
down the Light and Purity through them into these nether still unregenarted regions. If there is not this vigilance,
one gets absorbed in the unregenerated movement of the inferior layers and there is obscuration and trouble.
The safest way is to remain in the higher part of the consciousness and put a pressure from it on the lower to change. It can be done in this way, only you must the get the knack and the habit of it. If you achieve the power to do that, it makes the progres much easier, smoother and less painful.
