Here is an essay by Bhikku Bodhi about why he thinks there are so few Buddhist charitable organizations.http://www.thebuddhadharma.com/issues/2 ... entary.php
I've wrestled with these questions myself. Sometimes I wonder why my sangha doesn't do very much charity work. Personally, I would like to see more Buddhists helping the less fortunate. Even if my lama doesn't think it's so important, I would like to get involved with helping the poor because I think it's the right thing to do.
Where I live in Europe, there are homeless people who go through dumpsters for food and stray dogs that wander the streets.
The suffering of the world is so immense. Small acts of love and generosity are like tiny candles in the darkness.
Buddhist Monasticism and charity go hand in hand:
We see this in the Mauryan, where Emperor Ashoka builds rest houses for weary travelers, free hospitals for both people and animals, and wells and helped monasteries become institutions of learning such as Nalanda University and Vikramshila.
During the Tang Dynasty the monasteries fostered artistic creativity, cared for the sick, old, and orphaned, and ran community development projects such as developing roads and building bridges and wells.
Even today, in Southeast Asia, many monasteries serve as free accommodations, retirement homes, and homes for the homeless or chronically ill. Poor families frequently use monasteries as hostels. They serve as village libraries and centers of news and information, and the surplus money is used to make schools.
...as Buddhism spread literate culture into many societies in the process of political unification and organization, it is not surprising that the sangha came to wield political influence, or even political power, in a number of countries.
—Peter Harvey, An Introduction to Buddhism
Buddhism, was the first religion that inspired humanity to do good works and taught meditation to all, however, modern Buddhists hardly have the rigorous faith that the first Buddhists had, which is why there are fewer Buddhist charities today.
If Dharma is the best medicine -- it's something to be shared and spread to all --but without being pushy and obnoxious about it! I sit there and meditate in public! Makes people think
