Little children are so active and brisk to the point of causing annoyance to the parents. Maharishi will tell us the reason and then we will realize that getting angry with children is only because of the adult's ignorance.
What we should do is to channelize the child's energy in a constructive manner so that it may not harm itself or others. Cultivate kindness towards children whenever you happen to be in their company. Being harsh or rough to children is only a symptom of our spiritual in maturity.
