“Buddhism for this World” promoted by Master Yinshun is the mainstream thought of Buddhism in contemporary Taiwan.; Many Buddhist organizations including Dharma Drum Mountain are inspired by this thought and develop properously.; The charactistics of “Buddhism for this World” are based on the humanitarianism of Agaama Suutras and the loving-kindness and compassion of early Mahaayaana Buddhism towards all sentient beings.; Therefore, the “Buddhism for this World” is a movement, in certain aspects, of “returning to the India's primitive Buddhism and early Mah?y?na Buddhism.”; The proposing of this movement was inspired by Liang Shuming, a neo-Confucianist school in early 20th century with the color of humanitarianism and the loving-kindness and compassion sentiments, the “Buddhism for this World” has, obviously, the characteristic of “applying Confucianism into Buddhism.”; This paper aims to explain this subtle relationship between the “Buddhism for this World” and neo-Confucianism. In addition, the paper also compares it with Upaasaaka O-yang Jing-wu's movement of “Returning to India's citt?matra Buddhism” during the same period.; The latter didn't develop well.; The major reason: It never applies Confucianism into Buddhism.
