Every scripture or religion you read or follow has stated the importance of giving. In chapter 3, verse 12 of the Bhagavad Gita, Krishna says celestial controllers, being nourished and pleased by selfless service, will give you all desired objects. According to the Gita, there is a twofold path of spiritual discipline—the path of self-knowledge and the path of unselfish work for others. The Bhagavad Gita clearly says that you have to give back.
In Christianity, in its teaching piece from Jesus in the New Testament, Sermon on the Mount, “Blessed are the merciful: for they shall obtain mercy.” Or take the example of Saint Francis of Assisi, his prayer, Make Me an Instrument of Your Peace, where he says, “To be consoled as to console; to be understood as to understand; to be loved as to love and for it is in giving that we receive.”
Or you look at Islam; Muslims are mandated to give some part of their wealth, which is the concept of sadaqah or saddka. This concept is giving back out of compassion, love, friendship, and generosity with all truth. All religions highlight the importance of giving. A benefactor is a representative of God.
Each one has its own way. The important thing is giving. The giver, despite having the wealth, thinks that he is not the owner of the wealth, but the trustee of the wealth. This is the highest form of giving.
