Unconditional Love

Everybody regards, loves, likes, wants to eat red, beautiful, sweet, ripe mangoes. After sucking the juice of it, when it becomes residue- Pip(i.e.गुठली )or dry or sucked completely ,everybody wants to throw it off or throw it finally, assuming that it is useless. I have high regards for such type of brave people,who pay respect to the Pip(i.e.गुठली ) and Rind (i.e.छिलका)of the sucked mango also, and take care of it equally as they loved, liked, regarded and taken care of red ripe mango, when it was juicy,even after being aware that the Pip(i.e.गुठली ) and Rind (i.e.छिलका)of the sucked juice mango has nothing to give them back. Even then ,they try to use its pip to plant and reproduce again thousands of red ripe mangoes through its tree. Or try to pay back the obligation of the mango lifelong. 
-I do not know the meaning of above-may be applicable for mango, wife or beloved, cow or any other animal whose milk is used for our survival during our childhood, parents/elders who become old etc....lol...However, the above mentioned quality of people is essentially required for the people who are on the way to God or theist. 
This is the basic of Unconditional love, i.e. to love and serve for others without any hope of benefits from others and everybody must have this very basic quality ,as it is the ultimate height of worship of the God. Remember the services Mother Teresa.
