Source (Persian)
و وظیفۀ ایادی امر اللّه نشر نفحات اللّه و تربیت نفوس و تعلیم علوم و تحسین اخلاق عموم و تقدیس و تنزیه در جمیع شئونست از اطوار و احوال و کردار و گفتار باید تقوای الهی ظاهر و آشکار باشد
Translation
The obligations of the Hands of the Cause of God are to diffuse the Divine Fragrances, to edify the souls of men, to promote learning, to improve the character of all men and to be, at all times and under all conditions, sanctified and detached from earthly things. They must manifest the fear of God by their conduct, their manners, their deeds and their words.
