Norman Paulsen is a disciple of Paramahamsa Yogananda (sorry for the spelling). In his book Sacred Science he gives a meditation method that goes like this:
1 - While breathing in, feel the Life Force (prana) traveling along the spine from the coccis to back of the head.
2 - Hold a bit the breath
3 - Exhale feeling the Life Force descend through the hollow spine from back of the head to the coccis.
4 - Hold a bit the breath
Has anyone tried this meditation? What are the signs of progress?
Is it true that this meditation is similar to kriya yoga?
Thanks.
