When I took an opportunity of visiting Buddhist temples in Malaysia during July and August 2016, I came across an article, “My Remembrance of Kulapati Wang Hong—Fa,” written by Master Yin Shun. This article, however, can’t be found in any of his published works, such as 《妙雲集》、 《華雨集》and《永光集》. As a disciple of Master Tzu—Hang, Kulapati Wang Hong—Fa was widely known as Wang Nong—Shu, an extraordinary Buddhist woman who founded PhorTay Private High School in Penang. This school was a big success in many ways. This article has inspired the author to explore how Master Yin Shun had built a connection with Buddhists in Southeast Asia. Since Master Yin Shun settled in Taiwan in 1952, he went abroad a lot, visiting many countries and regions, such as Japan, the US, Thailand, Cambodia, Hong Kong, the Philippines, Singapore, and Malaysia, but he only “converted the local people by preaching when he was travelling around the Philippines, Singapore, and Malaysia.” During that time, he visited a lot of Buddhist temples around these countries, while giving lectures in which he expounded the texts of Buddhism and reaching out to some of the local masters. The aim of this paper was to observe Buddhists’ exchange activities between Taiwan and the abovementioned countries through Master Yin Shun’s efforts to convert people by preaching Buddhist principles in Southeast Asia. This paper describes in detail how Dharma Master Yin Shun made endeavors to convert the local people in Southeast Asia, and by so doing, presents the Buddhist exchange activities between Taiwan and some areas of Southeast Asia, like the Philippines, Singapore, and Malaysia.
