Fear God and keep His commandments both in your feelings and in your intellect. If you force yourself to keep them in your intellect, bit by bit you will attain to fulfilling them in your feelings.
Men who are leading a spiritual life see by the eyes of their heart how the devil lays his snares, how the angels guide us, and how the Lord, in His Sovereign power, allows the temptations, and how he comforts.
Let all of us who wish to attract the Lord to ourselves draw near to Him as disciples to the Master, simply, without hypocrisy, without duplicity or guile, not out of idle curiosity. He Himself is simple and not composite, and He wants souls that come to Him to be simple and guileless. For you will surely never see simplicity bereft of humility.
Walk before God in simplicity, and not in subtleties of the mind. Simplicity brings faith; but subtle and intricate speculations bring conceit; and conceit brings withdrawal from God.
According to the degree to which the intellect is stripped of the passions, the Holy Spirit initiates the intellect into the mysteries of the age to be.
May simplicity go before you everywhere; especially be simple in your faith, hope, and love, for God is an Essence of Simplicity, a Unity that is worshipped everlastingly, and our soul is simple. The simplicity of our soul is hindered by our flesh, when we please it.
Our holy fathers have renounced all other spiritual work and concentrated wholly on this one doing, that is, on guarding the heart, convinced that, through this practice, they would easily attain every other virtue, whereas without it not a single virtue can be firmly established.
