Sit quietly where you will not be disturbed.
Be aware of your Light Body, or Mer-Ka-Ba, if you can. If you cannot, then just be aware of a tube of light that is embedded inside your body. If you are Buddhist, you may be aware of this tube. It is similar to a fluorescent tube in that it is straight and glass-like and about the same diameter.
If you hold your middle finger and thumb together, that will be the size of your tube. It runs from one hand length above your head to one hand length below your feet. It enters your head at the crown chakra on the top of the head or, in other words, the place where a baby pulses directly after birth. It then leaves the body at the perineum, the soft place between the anus and the genitals, but continues between the legs to one hand length below the feet...
