A blessing is a reward.
We often hear, “What goes around, comes around.” It means the results of what one has done will one day affect the one who started the events.
Blessings are the result of our good deeds. I’m not a believer in karma, at least not in the traditional form. I do believe what you put into life is what you’ll receive. Be a blessing of happiness, and you’ll receive in kind.
A source of negativity will also receive in kind.
Negativity follows the same path. One who creates negativity will one day receive the same.
Be blessing to those in need and one day the same may be repaid to you.
