Biologically, "meditation" (Biblical Hagah) is the programming language of the Reticular Activating System (RAS). The RAS is a bundle of nerves at the brainstem that filters out unnecessary data, allowing only "relevant" information to reach your conscious mind.

When you "meditate day and night" on the Intel (Scripture), you are literally re-coding your RAS to spot opportunities ("hidden doors") that others miss. An "NPC" (Non-Player Character) operates on Automaticity—governed by the Basal Ganglia (habit loops). They walk into walls because their RAS is not programmed to see the door. Sakal is the result of a brain that has been physically re-wired through repetition to recognise the patterns of the Kingdom.
