Sushumnâ: It is very useful to meditate on the Sushumna. You may have a vision of it come to you, and this is the best way. Then meditate for a long time on that. It is a very fine, very brilliant thread, this living passage through the spinal cord, this way of salvation through which we have to make the Kundalini rise.
In the language of the Yogi, the Sushumna has its ends in two
lotuses, the lower lotus surrounding the triangle of the Kundalini and
the top one in the brain surrounding the pineal gland; between these
two are four other lotuses, stages on the way:
6th. Pineal Gland.
5th. Between the Eyes.
4th. Bottom of the Throat.
3rd. Level with the Heart.
2nd. Opposite the Navel.
1st. Base of Spine.
We must awaken the Kundalini, then slowly raise it from one lotus to another till the brain is reached. Each stage corresponds to a new layer of the mind.
