Jeos post above- Since you mentioned Yogi Bhajan can I ask you what do you think about the Kundalini Yoga introduced by him in the western world? I began practicing it very intensely some months ago and after doing a lot of research I find that Bhajan's yoga might be a mix of Sikh and hinduist health/religious/spiritual exercises...<!-- google_ad_section_end --> Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/hinduism/33304-gayatri-mantra.html
It's just a different art form of yoga.
However, when one's kundalini is awakened, that is a different matter.
No matter what people say, this can happen with or without the yoga.
When it happens, believe me, you know.
To me it doesn't matter if some one says it's a hindu thing or buddhist or oterwise.
It's DOES NOT BELONG to any group. It's about yourself and connecting with the 'naam' or god within you. See the thread on Naam jap,naam simran and meditation for more details. From this thread, you may hopefully find it easier to understand this one form of naam within you that you can connect to with simran.
