"O Momins, may God help you in deriving the fullest benefit from philosophy. May He guide you in thanking the Imams who are the highest authorities on this subject.

This world is not the original place of this receptacle (i.e., the soul). Its original place is somewhere else. The destination of its journey is the world of purity where there is light upon light. God leads to the light only those whom He likes. Think of this. Think of your precious souls. Close your ears to the earthly gossip of the meanest type and keep them open for an elevating talk. Use your intellect with which God has gifted you. It is only the fools who grope in the dark. Thank God for the favour that He has done to you by giving you every facility to seek your salvation and by providing you the Water of Life (i.e., the Holy Imams)."
