Forgive and pray, in order to live your life serenely. And do not do to others that which you do not want them to do to you, or return the evil which they have done to you.
We see that water gravitates from the mountains to low-lying areas; so too, the grace of God is poured out from the Heavenly Father upon humble hearts.
The virtue opposed to pride is humility. But as far as pride is loathsome and abominable, so welcome and lovely is humility to God and men. God Who is great and exalted looks on nothing so lovely as on an humble and compunctionate heart. Whence even the Most Holy Theotokos says of herself, For He hath regarded the low estate of His handmaiden. (Luke 1:48).
When you shed floods of tears during prayer, do not exalt yourself for this, as though you were above many others. It is that your prayer has received help from above, so that, having zealously confessed your sins, you may incline the almighty to mercy by your tears.
In the beginning, there is struggle and a lot of work for those who come near to God. But after that, there is indescribable joy. It is just like building a fire: at first it's smoky and your eyes water, but later you get the desired result. Thus we ought to light the divine fire in ourselves with tears and effort.
Put aside bodily considerations when you stand in prayer, lest the bite of a flea, a gnat or a fly deprive you of the greatest gain afforded by prayer.
