What the Sufi calls riyazat, a process of achievement, is nothing else than digging constantly in that holy land which is the heart of man. Surely in the depth man will find the water of life. However, digging is not enough. Love and devotion, no doubt, help to bring out frequent merits hidden in the soul, as sincerity, thankfulness, gentleness and forgiving qualities, all things which make man a true man, all things which produce an harmonious atmosphere, and all things which bring men in tune with life, the saintly life and the outer life. All those merits come, no doubt, by kindling the fire of love in the heart. But it is possible that in this process of digging one may only reach mud and lose patience. So dismay, discontentment may follow and man may withdraw himself from further pursuit. It is patient pursuit which will bring the water from the depth of the ground; for until one reaches the water of life one meets with mud in digging. it is not love, but the pretence of love, that imposes the claim of self. The first and last lesson in love is, "I am not - Thou art", and unless man is moved to that selflessness he does not know justice, right or truth: his self stands above or between him and God.
