Receiving without giving is a selfish act.
The joy of giving to others, be it friends, family, or people who are in need of help is unparalleled by another other joy.

A verse in Bible shows Jesus saying, “It is more blessed to give than to receive.”
Giving is an act that arises out of kindness and benevolence.
The joy that is thus received from it is one that is pure and will improve one’s overall mental health significantly.

Even in the Hindu context, it can be seen that one must always give to others.
The generosity of Karna can be cited for this.
There is another verse from the Bible that beautifully brings out the joy of giving.

It states, “Each one must give as he has decided in his heart, not reluctantly or under compulsion, for God loves a cheerful giver.”
