It is with deep concern indeed that he has learned of the difficulties you have encountered in your business, and [he] was particularly grieved to hear of the bitter competition you are meeting from some Persians in New York, who seem determined to ruin and force you out of business, despite the fact that you have shown them kindness, and refused to deal with them harshly. Though the Guardian would advise that you continue keeping such [a] true Bahá'í attitude of forbearance, he wishes you at the same time not to give way, and not to allow any threat on their part to discourage or demoralize you. However unethical the methods they may employ, it should be your firm conviction that such malicious devices cannot in the long run succeed, and that the most effective way of counteracting them is for you to maintain unreservedly the one true standard of business conduct inculcated in the Teachings.
