Today the magnetic power that attracts heavenly blessings is teaching the Cause of God. Whoever arises to perform this service the armies of the angels will grant him victory. The three conditions of teaching the Cause of God are the science of sociability, purity of deeds and sweetness of speech. I hope each one of you may become confirmed with these three attributes.
Therefore, one must be wholly cleansed from desire and self and passion, be abstracted (drawn apart) from the world of nature, become embodied light and visualized spirit and then be engaged in teaching the Cause of God. Then the fire of the love of God will flame so high as to attract the hearts of all mankind.
