Whenever I eat much, I do not need to eat for a while.  If one overindulges themselves in scripture, they may not digest it in the way that is proper, and may not be able to properly eat thereafter for a long time.

If mistakes that are made are accepted as a part of life, as a part of their creation, it may help them to grow stronger.  However, one must not become fanatical in trying not to make mistakes, as such fanaticism is not good.  Not wanting to make mistakes is one thing, and realizing the consequences for making mistakes is another, but perhaps paradise isn't just what one may all think it is, where every tree looks the same, or every step made doesn't create the possibility of snapping a sharp twig under one's foot.  One shouldn't go overboard not trying to make mistakes, but a person should maintain their zeal and efficiency of growth towards Father.  And for Father.

Father puts certain things in different people's hearts for different reasons, but all are righteous and just reasons.

If it is realized that snapping a sharp thorn under one's foot is a mistake, then one can make a better effort to not do the same twice.  In this, one may start learning to do things that may have only been dreamed about before, such as even being able to simply levitate with their energy over such obstacles.  This, though, would also be to put into reality different other symbolic characteristics that all must be within Father's Will.  Just because a person may be able to levitate doesn't mean that it should be practiced all the time with everything they do.  Proper balance.  One such cause for not levitating all the time could be in the deterioration of the physical muscle mass that Father has provided for usage.  All in Father's Will.
