A person who gives freely is loved by all. It's hard to understand, but it is by giving that we gain strength. But there is a proper time and proper way to give, and the person who understands this is strong and wise. By giving with a feeling of reverence for life, envy and anger are banished. A path to happiness is found. Like one who plants a sapling and in due course receives shade, flowers, and fruit, so the results of giving bring joy. The way there is through continuous acts of kindness so that the heart is strengthened by compassion and giving.

-- Buddha, Majjhima Nikaya
