Of course before one does a deeper practice of zikr one must control one's thoughts and feelings. If not one may do a great harm to oneself or others. We must not direct ill will, anger to anyone, not even to our worst enemy. If one creates compassion, we will tolerate, forgive, and take life easy. Then power increases. There are two things: one is to receive inspiration, the other is to gain power, jemal and jelal. Jemal is mercy and compassion; jelal is self-discipline and mastery over one's self.
