Self-acceptance or self-love, when approached from a spiritual level, is not superficial or conceit. Self-love is an honoring of our life-force by loving ourselves unconditionally no matter what flaws or traits or challenges we may have. We can still do inner work from a place of self-acceptance, and realize we can, as the following quote reminds us:
You are allowed to be a masterpiece and work in progress simultaneously. - Sophia Bush
We are all unique sacred expressions of Creation. How beautiful is that?
