This article explores the motives of volunteers of Buddhist Tzuchi Foundation in charity work from the standpoint of jen-ch'ing (human sentiments). The analyses are twofold. First, many people join Tzuchi for the purpose of accumulating merits for their family members, in particular, their parents. Or they tend to project their attachment for their parents and children onto their benevolent services. Women's familial roles and sentiments play a key role in this respect. Female members either extend their motherly love to their socio-religious services or define such services as their emotional outlet. Secondly, Tzuchi has developed on the basis of the emotional community formed by Master Chen-yen and her followers. The community features a charismatic cult. Members show their devotion to the group by virtue of group rituals and verbal expressions. On the one hand, they emphasize charitable behavior as Bodhisatteva's deeds. On the other hand, their commitment to the leading master is mixed up with the sentiments of filial piety. Also, members analogize their mutual relations as pseudo-relative ones. In this vein, Tzuchi can be characterized as “a big religous family.” The research demonstrates that charitable behavior is carried out, and persist, under the interplay between religion and culture, and that between the sangha and the laity with an emotional overtone.
