Missionaries
A mission is an important task one is given or gives oneself and missionaries are people who endeavour to spread their religion in a land other than their own.
Although there is no word in Buddhism for either of these things, the idea of promoting the Dhamma as widely as possible began with the Buddha himself and was important in Buddhism for many centuries. After the Buddha made his first disciples he said to them, ‘Go forth for the good of the many, for the happiness of the many, out of compassion for the world, for the welfare, the good and the happiness of gods and humans. Let no two of you go in the same direction. Teach the Dhamma which is beautiful in the beginning, beautiful in the middle and beautiful in the end. Explain both the letter and the spirit of the holy life, completely fulfilled and perfectly pure’ (Vin.I,20).
On another occasion he said that his disciples should, ‘speak about,’ ‘teach’ and ‘illuminate the Dhamma’ (A.II,51). Unlike some missionaries of the great monotheistic religions, Buddhist missionaries never collaborated with invading armies or colonial occupiers to spread the Dhamma. There are also almost no examples where force or legal sanctions was used to promote Buddhism. This is probably because of the teaching ethics the Buddha insisted missionaries should have. These included, ‘teaching the Dhamma with kindliness,’ ‘not for gain,’ and ‘neither for one's own or the other’s detriment’ (A.III,184).
The last great Buddhist missionary endeavour to meet with widespread success was the conversion of the peoples of the southern Himalayas (Kinnaur and Sikkim) during the 16th and 17th centuries by monks from Tibet. Today many missionary monks from Asia work to spread the Dhamma in Europe and America. Paradoxically and unintentionally, Christian missionaries have played a role in promoting Buddhism. The Buddhist revival in Sri Lanka in the 19th and in Burma in the early 20th century started in part as a reaction against the arrogance and aggression of some Christian missionaries.
