“That is the method practiced by all the prophets of all revealed religions from the beginning to the end. To help people purify themselves of destructive characteristics was the mission of Moses, of Jesus and also of the seal of prophets Muhammad, who was ordered by his Lord: “Purify them.” They all worked to this end and never despaired of success, as they had certainty that a treasure remained buried in people’s hearts. Look, if you have a precious diamond and then it falls into the toilet, are you going to flush it down with the dirties? Would anyone suggest such a thing? Perhaps some proud or weak stomached people might call for a servant to do it, but no one in his right mind would flush it away. Then when you retrieve that diamond you are going to wash it with soap and water thoroughly, perhaps dip it in rose oil, and then return it to your finger. No one is then thinking that the diamond is dirty. Diamonds do not absorb the qualities of what they fall into – souls are the same.”
