Doing dana through vegetarian diet

This is the second day of Kew Leong Ya Festival and devotees are still taking strictly pure vegetarian food. As a matter of fact, vegetation food is good for health as proven by those who are sick. By swifting from meat food to vegetarian ones, the digestive system can function better.

As a Buddhist, I am made to understand that taking vegetarian food is doing dana, that is refraining from killing. If more people swift to vegetarian diet, more killing of edible birds and animals can be prevented. Those who practise taking vegetarian food will have a longer life.
Hence we know that taking vegetarian not only enables one to do dana but also prolong one's life.
