In the Bhagavad Gita, Lord Krishna says, “You cannot get into yoga (union with the self) unless you drop the desires in you.” So the question is how to drop desires. Meditation is the art of letting go your desires.
Marriage means sacrifice. Sacrificing your desires for the good of the other and for the sake of the whole family.
Marriage is an institution where you come out of your small self to start caring for someone else, for everyone.
