G'day Alex,
The seven steps are taught with the eyes open. It isn't mentioned in the manual, but is in the tapes, and is taught that way in person. It is very hard to try and do it with your eyes closed and keep your balance.
I actually found that the opposite helped, for me, as far as coming out of having my eyes closed for quite awhile, then opening them and doing seven steps. If I looked at a source of light, like a candle or daylight(just for the first few steps), it seemed to help 'open' my eyes, and feel more balanced. Or just opening them wide, for a few seconds , shifting to eyes open.
love,
gallen
