In my experience children have mental problems as a result of their mothers’ increased sexuality.
When children’s energy fields are being formed, the energy which should have been spent on children’s conscience, on concentration and on seeing the whole picture, this energy can be wasted though the increased sexuality of mothers.
Therefore if a family has a history of increased sexuality, then the children in such family can have mental problems, or become criminals who can’t control their feelings and so on.
In order to help your descendants, if you’ve done something like this in the past, you need to go over events in your life, when you substituted love with lust.
You need to repent, pray and let go of offence from the opposite sex. All this is should be done whilst fasting and feeling detached.
