Okay, I have been reading about ways of opening the microcosmic orbit and one way is the cool draw technique known as testicle breathing. Another I have read is about imagining a small white pearl at the lower dantian and then orbiting the pearl around the back and front channel with intention to feel at the same time as visualization. Do you guys think the deer exercise can help open this orbit? And, can you guys tell me what techniques you use to open the microcosmic orbit?
