Little or a Lot

Excerpted from What Makes You Not a Buddhist, ©2008, by Dzongsar Khyentse Rinpoche:

One day a monk noticed a tear in Gautama Buddha’s robe and offered to stitch it, but Buddha refused his offer. He kept walking and begging alms in his torn robe. When he headed toward the hideout of a destitute woman, the monks were puzzled because they knew that she had no alms to offer. When she saw his torn robe, the woman offered to mend it with what little string she had. Siddhartha accepted and declared that her virtue would allow her to be reborn in her next life as a queen of the heavens. Many people who heard this story were inspired to acts of generosity of their own.

There's a very similar story in Christianity.  From Mark 12: 41-44:

And Jesus sat over against the treasury, and beheld how the people cast money into the treasury: and many that were rich cast in much. And there came a certain poor widow, and she threw in two mites, which make a farthing. And he called unto him his disciples, and saith unto them, Verily I say unto you, That this poor widow hath cast more in, than all they which have cast into the treasury: For all they did cast in of their abundance; but she of her want did cast in all that she had, even all her living.
