Meditation - Raising Kundalini

[derwyd]

I am currently in the process of raising my kundalini. I took Robert Bruce's advice in his book to not use chakra 1 and 2. I start by drawing energy into the Navel or sub navel and up through the crown. I ran into some issues though. I got further into meditation, but at one point I could not breath and at that same time my hands went from the mudra that I usually use to open up like i was catching a ball that was coming down, and then my hands started to bend outward very uncomfortly.

Does this mean anything, or is it expected?
