Let us remember the basic principle of love
The attachment for one’s own body and its extensions like
children and relatives is actually developed on the basis of the real
living entity. As soon as the real living entity is out of the body, even
the body of the most dear son is no longer attractive. Therefore the
living spark, or eternal part of the Supreme, is the real basis of
affection, and not the body. Because the living entities are also parts
of the whole living entity, that supreme living entity is the factual
basis of affection for all. One who has forgotten the basic principle of
his love for everything has only flickering love because he is in maya.
The more one is affected by the principle of maya, the more he is
detached from the basic principle of love. One cannot factually love
anything unless he is fully developed in the loving service of the Lord.
