Apparently, from what I am reading on the Advanced Yoga Practices forum (google it), Kechari is really necessary if you want to make rapid and profound changes in your energy body. The stuff I have read from other peoples' experiences have me sold completely.

Its actually not as hard to do as it seems. look up kechari on youtube.com, there are a ton of videos on how to do it.

I am actually quite close myself, I should be able to acheive it in the next week.
