दातृयाचकयोर्भेदः कराभ्यामेव दर्शितः ।
एकस्य गच्छताधस्तादुपर्यन्यस्य तिष्ठता ॥

- बृहत्कथा

The difference between the donor and the beggar can be known by looking at the position of their hands. The donor's hand point downwards and that of the beggar extends upwards. This is sometimes used as an idiom to describe a person. (Ex: Charudatta was such a good person that his palms always point downwards)
