Lost myself during exercises

["YaGi" <yagi@...>]

Hi,

I'm on step I and have some difficulty with doing the thought control
exercises and impregnation of the air.
The problem is a luck of concentration. I'm starting my exercise right and
after a while i'm lost in some thought or in a dream like state.
Do anyone has some hints how to improve my concentration?

Best Wishes

YaGi
