A wise shaman once told me to start each day by "bringing my full attention to my intention." By that he meant pay close attention to what you are actually intending to do with your time, energy, skills and love. The purpose is to fully engage in your destiny by choosing and creating specific patterns and thoughts.
The hook is to quiet the mind enough to notice our reactive nature and not react against our intentions.
In Tibetan language there is a word called Shenpa. Shenpa is the urge, the hook that triggers our closing down and separating. It's an addictive response that feels like attachment.
By pausing and bringing our attention inward and back to our positive intentions, we can learn how to unhook right at that moment when something uncomfortable is presented to us. We decide not to go crazy about it. We let go of the rope and make peace right then and there. It doesn't mean we aren't confused, overwhelmed, angry or hurt. It just means we can sit back and let it wash over us without causing ourselves or others harm. Usually it wasn't that big of a deal and we forget about it quickly anyway. That's real "letting go."
If we start each day with the intention of not causing ourselves or others harm we are growing our practice of loving-kindness. This way of being is nice. It makes life more pleasant for everyone.
