Gurudev : You get strength from sacrifice. It increases your valor.
Sacrifice brings you so much peace, and you feel that your life is fruitful. You never get as much happiness by craving or acquiring things, as much as you get by sacrificing them.

When we give something to someone, don't we get happiness? What pleasure you get in giving is more than the pleasure you get in receiving. Of course there is happiness in getting the things you have desired for, but the happiness which you get by giving and sharing is double.

Only those who have something can give something. That is why, sacrifice, the pleasure of giving is one level higher than the pleasure you get in receiving."
