From the book "Jap Ji – The message of Guru Nanak", written by Sant Kirpal Singh

 

Now we will see whether there is a possibility of communion between the microcosm and the macrocosm. Man is an epitome of the macrocosm. There are in man nerve centres, lying in a dormant state, and these can be quickened by the practice of the Divine Word – the Sound Principle.

There are six reflex centres in the Pind or the body, corresponding to the six centres in the Brahmand or Cosmos. These in their turn, are reflections of those in Par-Brahm or the purely spiritual region.

The lower six centres are the ganglions at the rectum, the generative organ, the navel, the heart, the throat and the sixth midway between the eyebrows, which is called Til or Ajna (see stanza XXI of the Jap Ji) and is the seat of the soul in man. It is from here that the spirit-current descends into the body, giving life and strength to the physical frame and its respective limbs. This spirit-current plays an important part in the nourishment of the body and if this is cut off from any part, it loses all vitality and forthwith ceases to function.

The six centres of the Brahmand and of the spiritual regions are also to be found within us. When the spirit-current is brought into play with these centres, one can have contact with their corresponding planes.
