What is the third model of reality(islam) all about?
I’m going to assume that this question is “What is Islam?”
The short answer to this question is that Islam is a religion that emphasizes the idea that pride is a problem and submission to God is the solution.
Other religions emphasize other problems. Christianity sees sin as a problem and salvation as the solution. Chinese Buddhism sees chaos as a problem and social order as the solution. Judaism sees exile as a problem and return to God is the solution.
