Repeated intense indoctrination of the children even changed the perception of some of the charlatan mullahs so that they, themselves, believed their own lies, took their own keys to Allah’s paradise and rushed to their death…
It is important to understand that the human mind is not a perfect discerner of the objective reality. It is said that beauty is in the eye of the beholder. Similarly, it can be said that reality is in the mind of the beholder. The outside world only supplies bits and pieces of raw material that the mind puts together to form its perception—reality. Depending on the type and number of bits and pieces that a given mind receives and its already in-place data, its reality can be very different from that of another mind.
The more prescribed and homogeneous a group, the greater is the group’s consensual reality, since the members share much in common experiential input and reinforce each other’s’ mindset. Thus, members of a given religious order, for instance, tend to think much more similarly to one another than to members of other groups with different experiential histories.
Various approximations of the objective reality, therefore, rule the mind. The degree to which these approximations deviate from the larger group’s consensual reality determines its delusional extent and severity.
A narcotic mainliner, for instance, under the influence of the drug, may become convinced that a bug is burrowing under his skin. In his absolute, although clearly false, certitude of the reality of his perception, cocaine users are known to take a knife to their own body to dig the burrowing bug out before it has penetrated too deeply.
A methamphetamine user’s reality is often distorted in a different way. Under the influence of the drug, an intense paranoia overtakes him. His reality is dominated by the belief that one or more people are lurking about to harm or kill him. He may wield a deadly weapon, going from room to room, from closet to closet, in search of the assailants.
If you believe that a bug is camping deeply in your body, then you might go ahead and try to dig the non-existent bug out. If you believe that people are lurking around the house to harm or kill you, you go after them before they get you. If you believe that all the troubles of the world are due to the evil-doings of the non-Muslims who war against Allah, then you do all you can to fight and kill them, particularly since Allah tells you in the Quran it is your duty to do Quran so. (2:191-193) (3:151)
The drug-induced delusions are hallucinations. They are dramatic and usually transitory, while religiously-based implantation of ideas program the mind with lasting delusions.
