A Developed Personality
The Quran likens a true man to a plant. (The Quran, 14:24-25) Just as a plant grows into a tree, so does a person’s personality grow like a lush tree, until it becomes a developed personality. Physically, man is born as an infant and then grows into a full man. If man’s thought process continues healthily, the human mind would reach the stage of development in the same way as does its body.
This thought process naturally runs through every human being. All one has to do is protect oneself from the things that hinder his thought process. An unobstructed thought process continues to flow like a spring that sprouts fresh water.
