Re: relaxing during technique - how?
As the word is relax and not lax it's best to look at it's root. From latin 'to undo' and re 'again'.
Tells you something right there. You have tied up, tensed up, so time to find where you are tying up and learning how to undo it. It's a process and practice and thus you develop the ability bit by bit.
So the question is not whether I am relaxed or not it is more 'where am I not relaxed' and there lies the next challenge.
Spiritually or mentally 'holding on to' makes the body tense. Solution---spiritually and mentally learn bit by bit to let go.
The more you let go the more you can flow. It's all good.
