When we are emotionally attached to the outcome, we become powerless because in practice, we have absolutely no control over the final result. We are emotionally attached to something we cannot control.
When we do our best and don’t care about the outcome, we embrace our personal power because it’s up to us and only us to do the best we can.
The whole concept of success and failure is ridiculous. Failure is learning and success is confirmation that we’ve learned.
By definition, all polarity is based on separation, and separation is the realm of our Ego.
Among many other things, the Bhagavad Gita shows us how to let go of our own Ego, so that we can express ourselves freely in higher dimensions, while remaining in the Human body.
