Yes, we dare say that there will be times when they will be hurt, but earth life is for learning. Let them learn in their own way, of their own choosing. In the future earth schools will be very different. We are not altogether in favour of your school training now. It seems very limiting.
Children often emerge from school life with very little knowledge of matters of most importance.
Quite often they emerge with the 'stuffing totally knocked out of them', very little in the way of self worth. We would recommend that you 'shop around' for a good spiritually - based school. In the future these will not be so few and far between. Look for schools which encourage learning in a more natural sense. In our society children are raised with the utmost care and attention.
