Premanand Maharaj Ji
Is it wrong to love my children very much and suffer when they are hurt?
See Bhagwan in your child
Loving one's child is natural, but seeing Bhagwan in the child destroys moh. Love with that awareness and the bond becomes a cause of liberation.
Love knowingly, and the love that is the cause of bondage through moh becomes the cause of liberation, when you love your son with the feeling of Bhagwan in him.
