“The spirit hates sin, but the flesh and the soul are sympathetic to it and cling to it because they are clothed in passions. Goodness or the will of God are beloved by the spirit, but the body and soul are not sympathetic to it…Self-opposition and self-forcing — these are the two aspects of zeal born in the soul, forming as it were the beginning of asceticism. Both of these comprise the struggle of man with himself, or to put it another way, podvig.”
(St. Theophan the Recluse in ‘Path to Salvation’)
