I used to meditate a lot as a kid and focus on pulling energy to what I now know is the Dan tien. I started getting back into it within the past month or so and in that time I've passed out in the shower twice. I haven't found any existing techniques that fit my needs so have been working on my own.
Description of what I do: sit in normal cross-legged (not lotus) close my eyes and expand my senses to feel the energy around me and focus on pulling it in as I breath deeply into my stomach. Then I contract my stomach and slowly breath out trying to focus on storing the energy as a pearl. Any insights or help would be greatly appreciated.
