Is it ok to use headphones when practicing the Small Universe meditation, or do you lose something by not having the ohm and mah sounds out loud? Is it ok to use headphones with the self concentration meditation and the active exercises?
I have sometimes used headphones, mostly haven't and I haven't noticed a difference. You can also do it without the tape with good effect, but I really like Master Lin's 'presence'for choice - it's kind and comforting.
