Meekness and humility of heart are virtues without which it is impossible to inherit the Heavenly Kingdom, to be happy on earth, or to experience inner calm.
Knowing the exact nature of everything, God permits each person to be tested according to his strength. As St. Paul puts it: 'God is to be trusted not to let you be tried beyond your strength, but with the trial He will provide a way out, so that you are able to bear it' (1 Cor. 10:13).
Meekness is the fellow-worker of obedience, the guide of the brotherhood, a bridle for the enraged, a check to the irritable, a minister of joy, the imitation of Christ, something proper to angels, shackles for demons, a shield against bitterness.
When tested by some trial you should try to find out not why or through whom it came, but only how to endure it gratefully, without distress or rancor.
Imitate the Publican and you will not be condemned with the Pharisee. Choose the meekness of Moses and you will find your heart which is a rock changed into a spring of water.
But if you give a strong body rest and ease and idleness, all the passions dwelling in the soul are intensified. Then, even if the soul has a great desire for good, even the very thought of the good that is desired will be taken from you.
