If someone offends you, don't tell anyone about it except your elder, and you will be peaceful. Bow to everyone, paying no attention whether they respond to your bow or not. You must humble yourself before everyone and consider yourself the worst of all. If we have not committed the sins that others have, perhaps this is because we did not have the opportunity - the situation and circumstances were different. In each person there is something good and something bad; we usually see only the vices in people and we see nothing that is good.
If you offer fasting with humility and with mercy, your bones, as Isaiah said, shall be fat, and you shall be like a well-watered garden (cf. Isa. 58:11). So, then, your soul shall grow fat and its virtues also by the spiritual richness of fasting, and your fruits shall be multiplied by the fertility of your mind, so that there may be in you the inebriation of soberness, like that cup of which the Prophet says: 'Your cup which inebriates, how excellent it is' (Ps. 23:5 LXX)!
A good youth ought to have a fear of God, to be subject to his parents, to give honor to his elders, to preserve his purity; he ought not to despise humility, but should love forbearance and modesty. All these are an ornament to youthful years.
