I have been contemplating my breath as per your instruction. I need further direction because I think ran into some problems:
I inhale and expand my tummy, hold my breath for 2-5 seconds and then exhale. Often when I hold my breath, my stomach starts making bubbling noises even as air comes out from my mouth. While I contemplate my breath, I feel very comfortable. If I prevent the air from escaping then I feel a little bit of discomfort. Also, I pass gas while I meditate but I still feel as comfortable as before.
Is there anything wrong with my practice? Please clarify it for me. After I started following your meditation methodology, I feel better and can sleep better. For that I am very grateful and wish you great health.
