The secret to maintaining one’s spiritual progress

I ask the Blessed Beauty to assist you and confirm you. Wherever I go, you will be in my thoughts. I shall not forget any one of you. I beg of God that you may become more enlightened, more severed, more spiritual, more aflame and that you may be humble and submissive, for as long as man does not consider himself to be good but regards himself as weak and deficient, he progresses; but the moment he considers himself good and says, `I am perfect', he falls into pride and retrogresses. (Words of ‘Abdu’l-Baha when leaving Chicago, September 17, 1912, ‘Mahmud’s Diary’)
