True self mastery means being authentic in all that we say and do and it takes 100% honesty and transparency. Whatever you do, prove with your heart, if you do it to please others or because it is what your heart tells you to do.
Often we act non authentic, because we want to please others in an attempt to avoid our fear of being abandoned or rejected.
However the pain we inflict on ourself by being untrue and unauthentic is far greater than a potential pain of being abandoned. When we honor our self in being true to self, we transcend the fear of ego of being abandoned and naturally attract people who honor us in our truth too.
