When you find yourself flying it is always the vital being in the subtle body in the vital world that is doing it.
It is a very usual experience. It means that for a moment you were no longer in your body, but somehow either above or somehow outside the body-consciousness. This sometimes happens by the vital being rising up above the head or, more rarely, by its projecting itself into its own sheath (part of the subtle body) out of the physical attachment. But it also comes by a sudden even if momentary liberation from the identification with the body-consciousness, and this liberation may become frequent and prolonged or permanent. The body is felt as something separate or some small circumstance in the consciousness or as something one carries about with one etc. etc., the exact experience varies. Many sadhaks have had it. When one is accustomed, the strangeness of it (dreamland etc.) disappears.
When the mind is silent there is peace and in the peace all things that are divine can come. When there is not the mind, there is the Self which is greater than the mind.
The silence and peace are themselves part of the higher consciousness — the rest comes in the silence and peace.
