You could just decide. You really could - wherever you are, whatever you're doing - you could just decide to Let Go right now. Let go of everything you might have been striving or efforting for, every goal, dream or aspiration. Every fear or worry. You could simply say "enough is enough, I let go!" And if you were to do that deeply enough, you'd come home - to who you really are. You'd realise this was the real purpose behind everything; the real meaning.
