Hawzah News Agency - God, the Immaculate, thus describes to the Noble Prophet how one should comport oneself in a scholarly or religious circle:

When those who have faith in Our signs come to you, say, “Peace to You”.)6: 54)
 

The intermediate among those thus saluted by the Prophet simply hear his salutation, whereas the elite
will hear God’s salutation through His Prophet. Thus God salutes the prophets, His friends, and the faithful.
 

God’s salutation is not verbal. This salutation is, rather, an effusion unto the sound heart. God’s word is
His action; God’s salutation is His nurturing the sound heart. What is a sound heart? It is the heart that has unified its cognitive (darki) and emotive (tahriki) faculties. An unsound heart, on the other hand, is that which has lost control of these faculties.
 

One who fails to attain to inward unity will also fail in outward unity. If imagination roams unrestrained,
lust and anger perpetrate what they will, and base faculties subjugate the intellect (“How many an intellect that is a slave to unruly desire”), one is lost in confused  thoughts, and one so lost cannot be a member of a unified community. One who fails to attain to unity is impotent: disorganized multiplicity is
unprolific.
 

In this light, a sound heart is a heart that has unified its desires, impulses, and cognitions. And it is only
after achieving this inward unity that one may legitimately advocate unity in the social sphere.
