My Pilgrimage to the Spirit

March 10, 1932

If by Centres you mean "Chakras" these are seven:

1) The thousand-petalled lotus on the top of the head.

2) In the middle of the forehead—the Ajna-Chakra-(Will, Vision, Dynamic Thought). It is not called the psychic eye.

3) Throat-Centre—Externalizing mind.

4) Heart-lotus—Emotional Centre in front, Psychic behind it.

5) Navel—Higher Vital (Proper) Centre.

6) Below Navel—Lower Vital Centre.

7) Muladhar—Physical Centre.

All the Centres are in the middle of the body, not on left or right; they are supposed to be attached to the spinal cord; but in fact all these things are in the Sukshma Deha, though one has the feeling of their activities as if in the physical body when the consciousness is awake.
