Each and every reader comprehends the Holy Qur’an on a different level in tandem with the depth of his understanding. There are four levels of insight. The first level is the outer meaning and it is the one that the majority of the people are content with. Next is the Batm—the inner level. Third, there is the inner of the inner. And the fourth level is so deep it cannot be put into words and is therefore bound to remain indescribable.
