Imam Khomeini once said that "Prophets came and brought laws. Divine books were revealed to them to prevent application and intemperance of nature and to bring the human self under control of the law of intellect and canon, making him edified and tame him so as not to behave beyond the limits of reason and canon. Therefore, any soul that adjusted his qualities to Divine laws and intellectual criteria will enjoy felicity and come under the category of people who have been delivered from adversities."
Hence, a greater Jihad (spiritual struggle) of realizing 'idalah in the self is precedent to other struggles.
First, one should begin with oneself, because as long as one pays attention to the self, the self wants everything for him. And all difficulties originate from attention to the self and selfishness.
"When there is no faith and all man's attention is concentrated on one's self and he wants everything for the self, then problems arise. These conflicts are between selfishness. If all the saints of God got together somewhere, they would never conflict with each other. They would never disagree each other, because all of them work for God, from one source, and in one direction.
From Imam Khomeini's viewpoint, this movement enables one to realize 'idalah and moderation, abstain from intemperance and extreme views in affairs, move within the framework of the criterion of intellect and canons and, thus, attain real happiness.
