For know thou well, that fleshly desires and unreasonable likings in meat and drink, or any likings that belong to the body, exceeding reasonable needs, though they be not always great sins to him that is in charity. Nevertheless, to a soul that desireth cleanness and purity of heart, and a spiritual feeling of God, they are full heavy, painful and bitter, and greatly to be eschewed; for the spirit cannot feel his kindly savour within, till the flesh hath lost his beastly savour without. (John Climacus)

By grace and with discipline we ought not exceed reasonable needs.

We are better in every way when our body is rested and clean, our appetites are modestly filled, and we use our senses and strength in good work.

Our bodies are our principal temple. Here we can meet God each day and every minute. Our temple ought to be a place of peace and inspiration focused on our relationship with God.
