Over the years I have learned to be sceptical about my feelings, I have noticed that they are not the 'truth'. For example I rarely 'feel' like practicing. I'll 'feel' a bit tired, and when I begin it may feel as if my body is heavy, and my mind is anywhere but here in the practice. I have learned to mistrust these feelings and stay with the practice, over and over I have seen my mind calm down and my body wake up.So now I will practice whether I feel like it or not. The feelings pass, they were not real. On the odd occasion that the tiredness persists and hasn't been replaced by joy and enthusiasm for and in the work, I'll stop, this IS the time to rest and recharge.
And so I have come to trust the practice to let me know how my body is.
