The acceptance of oneself is the essence of the whole moral problem and the epitome of a whole outlook on life. That I feed the hungry, that I forgive an insult, that I love my enemy in the name of Christ — all these are undoubtedly great virtues. What I do unto the least of my brethren, that I do unto Christ. But what if I should discover that the least among them all, the poorest of all the beggars, the most impudent of all the offenders, the very enemy himself — that these are within me, and that I myself stand in need of the alms of my own kindness — that I myself am the enemy who must be loved — what then? As a rule, the Christian’s attitude is then reversed; there is no longer any question of love or long-suffering; we say to the brother within us “Raca,” and condemn and rage against ourselves. We hide it from the world; we refuse to admit ever having met this least among the lowly in ourselves.
– Carl Jung in Memories, Dreams, Reflections
You cannot apply kindness and understanding to others if you have not applied it to yourself.
