This is the greatest skill of all, to take the bitter with the sweet and make it beautiful, to take the whole of life in all its moods, its strengths and weaknesses, and of the whole make one great and celestial harmony.

Be constant in your practice, and one day the One who gave you the desire for the prayer of the heart will give you that prayer itself. When your heart's intention is fixed on God, it will keep lit the incense of your prayer, and wind of distraction will not put it out. do not worry about stray thoughts; they may come and go, but they will not take your attention away from God.
