The sensations shouldn’t interfere, though if you’re leaking energy from your hands, rather than just storing it there, that could make things slightly more difficult. Feel it out, and if it seems to be causing trouble you’ll probably have to learn to close the valves in your hand that release that energy. At least that’s the best way I can explain it.
I just did day 7 also. It was hard to get going, probably because I’m tired. I also find that I go slower with all of this than he recommends. I’m going to trust my own body though. Also, I’m really unsure how to coordinate this with my breath. I breathe slowly naturally, and find if I try to raise energy while exhaling or lowering energy while inhaling it’s very difficult. I might need to look this up in astral dynamics. It’s probably something I’ll have to keep working on though. Any ideas from the energy folks here?
