"The heart is refined, spiritual, and heavenly by nature - guard it; do not overburden it, do not make it earthly, be temperate to the utmost in food and drink, and in general in bodily pleasures. The heart is the temple of God. 'If any man defile the temple of God, him shall God destroy' (I Cor. 3:17)."

When hungry, do not throw yourself upon food - else you will overload your heart and body. Eat slowly, without avidity, with reflection to the glory of God, remembering the God Who feeds us, and above all His incorruptible food, His Body and Blood, that out of love He has given Himself to us in food and drink, remembering also the holy word of the Gospel.
