Heat is just purification...I hope everyone's clear on that. If not, people could start reading this and do kechari just for the heat...and possibly not ever experience any! That would get pretty confusing. I hope everyone is clear on what they're seeking, in doing these practices. Enlightenment!
Shweta,
Here's a tidbit about purification from the Hatha Yoga Pradipika:
"12. In the beginning there is perspiration, in the middle stage there is quivering, and in the last or third stage, one obtains steadiness; and then the breath should be made steady or motionless.
13. The perspiration exuding from exertion of practice should be rubbed into the body (and not wiped), as by so doing the body becomes strong.
14. During the first stage of practice the food consisting of milk and ghee is wholesome. When the practice becomes established, no such restriction is necessary."
- From Book II : Pranayama
So you being showered in your own sweat and shaking will end up passing. Rubbing your sweat back in, and drinking milk and consuming ghee is up to you, although I think it'd be good to do those things. It can't hurt, right? In my experience, it helps the purifications pass quicker.
Also, I don't suggest backing off! Unless in your daily life you notice that you're being way too flakey or emotional...or you have ongoing heat, like Meg has. Purification isn't a sign to self pace...things that mess with your day to day life are. At least that's my view on the issue.
It's good that your meditation was waaaaaaaay deep, but it's better when you take that deepness into your daily life...when the world begins to unite as one thing in your mind. Then you're always meditating, without trying. You can't help it. You get absorbed in everything, like watching a great movie where you forget about everything but what's going on in it. This is one-pointedness.
Someone could have the deepest samadhi when they sit for twenty minutes, but if it isn't integrated with going through your day, what use is it? You come out and are still in delusion. I'm quite sure this is where Yogani's up and coming Self-enquiry book will take us. To enlightenment!
Anyway, sorry I'm giving advice to you long time AYP folks. I apologize if you know all of this already, and I'm just coming off as a "look at me I know everything" type. We're all on the same path, and I haven't yet reached the end...so I assure you I don't know it all...I'm just trying to help.
