It is not necessary that the Sufi should offer his prayers to God for help in worldly things, or by thanking Him for what he receives, although this attitude develops in man a virtue that is necessary in life. By the thought of God, the whole idea of the Sufi is to cover his imperfect self even from his own eyes, and that moment when God is before him, and not his own self, is the moment of perfect bliss to him. My Murshid, Abu Hashim Madani, once said that there is only one virtue and one sin for a soul on this path: virtue when he is conscious of God and sin when he is not. No explanation can be sufficient to describe the truth of this except the experience of the contemplative, to whom, when he is conscious of God, it is as if a window is open which is facing Heaven, and, when conscious of the self, the experience is the opposite. For all the tragedy of life is caused by consciousness of self. Every pain and depression is caused by this, and anything that can take away the thought of the self helps to a certain extent to relieve man from pain; but God-consciousness gives a perfect relief.
