What I mean about whistling is the act of whistling itself. I'll just use my own culture. For example, it is forbidden to whistle in the home during the night because malevolent spirits might hear it and try to do negative stuff in the home or to the person doing the whistling.
Many of these beliefs are just lies based on ignorance and violence; this is a primitive method of making people obedient to certain things through fear.
A related example I can give is a stupid belief about old wood-burning ovens. It is about strictly putting a few branches of wood into the oven after use, otherwise it will error 303.
They don't give you any explanation or knowledge, they just tell you that if you don't do as the programming says, it's no good and it's an evil act and they use violence to convince you.
More than likely, the reason for this is to dry some of the wood branches with the residual heat from the oven to make it easier to light the fire for later use of the oven.
This method is the worst education and teaching that can be done, the enemy still uses this method but for different purposes.
As for things that might have to do with spirituality, the enemy has removed almost all knowledge about spirituality and what is left has corrupted it and therefore, what they might understand and experience is irrelevant, useless and in the worst cases can even be dangerous.
