By the righteousness of the one true God! Were anyone to wash the feet of all mankind, and were he to worship God in the forests, valleys, and mountains, upon high hills and lofty peaks, to leave no rock or tree, no clod of earth, but was a witness to his worship—yet, should the fragrance of My good pleasure not be inhaled from him, his works would never be acceptable unto God. Thus hath it been decreed by Him Who is the Lord of all. How many a man hath secluded himself in the climes of India, denied himself the things that God hath decreed as lawful, imposed upon himself austerities and mortifications, and hath not been remembered by God, the Revealer of Verses. Make not your deeds as snares wherewith to entrap the object of your aspiration, and deprive not yourselves of this Ultimate Objective for which have ever yearned all such as have drawn nigh unto God. Say: The very life of all deeds is My good pleasure, and all things depend upon Mine acceptance.
