The religion of Islam is not a mental exercise, or on the level of reason alone. It is understanding the basic elements of it AND their realization (tahqíq) by practice, while following the sunna of Prophet Muhammad ﷺ.
”The Sufis distinguish between various "states" (ahwál) which one may experience upon the path to God and the "stations" (maqamát) which one must pass through in order to reach Him. In general the states are fleeting and may or may not come, while the stations are the necessary foundation for actualizing human perfection. …
”For the moment it is enough to recall that one of the standard ways of distinguishing between states and stations is to say that states are divine "bestowals" (mawáhib), while the stations are "earnings" (makásib). In a similar way, knowledge acquired through tasting is a bestowal. Nevertheless, this does not mean that God may give tasting to just anyone. The servant must first have exerted himself and made himself worthy of it. The Shaykh uses the term "opening" (fath) in the following as a near synonym for unveiling.”➟
