For any change to take place you have to come to an unconditional acceptance. This, to dissolve the resistance and conflict within that obstructs the return to the zero point, the stillness needed for any spiritual transformation to take place. You can never do that from a place of avoidance or antagonism.
And for any change to last you have to integrate it within yourself so that it becomes an internal reality. This, to retain stability regardless of external disruption. If the change is only a cosmetic exercise then it’ll only last until something else bumps it out of the way. But nothing can intrude or cover your heart.
