One of the aspects of the teachings of ‘Abdu’l-Bahá which impresses me is that of concentrating on one’s own spiritual development and not dwelling on the faults of others.
‘Wherefore must the friends of God, with utter sanctity, with one accord, rise up in the spirit, in unity with one another, to such a degree that they will become even as one being and one soul. On such a plane as this, physical bodies play no part, rather doth the spirit take over and rule; and when its power encompasseth all then is spiritual union achieved. Strive ye by day and night to cultivate your unity to the fullest degree. Let your thoughts dwell on your own spiritual development, and close your eyes to the deficiencies of other souls. Act ye in such wise, showing forth pure and goodly deeds, and modesty and humility, that ye will cause others to be awakened. Never is it the wish of ‘Abdu’l-Bahá to see any being hurt, nor will He make anyone to grieve; for man can receive no greater gift than this, that he rejoice another’s heart. I beg of God that ye will be bringers of joy, even as are the angels in Heaven’.
