What we resist, persists. Resistance is often connected to the story teller in our minds. Non acceptance is wanting the moment to be something other than what it is.
When we focus of what not in our control, we freely give our power away. Our minds are not who we are, it is our tool to help us experience our lives from either a contracting energy or an expanding energy.
Acceptance allows us to live in the moment without the need for a story that projects us into the past or future. It is what it is.
