Firstly I interpreted Ven. Yinshun’s emphasis upon human world and human beings in his ideas of "Humanistic Buddhism." Secondly I pointed out that there are two ways of justification for animal protection in Buddhism, one is the theory of Dependent Arising (prat?tya-samutp?da) and the other is the doctrine of Buddha Nature (tath?gatagarbha) . By contrast to the ontological assumption of "endowment of animal rights via tath?gatagarbha," Ven. Yinshun’s "Humanistic Buddhism" lay more stress on the theory of Dependent Arising, justifying "all sentient beings are equal" from equality of sensitive feeling, equality of Dharma nature, and equality of the potentiality to achieve Buddhahood. Thirdly, under the doctrines of "dependent arising and emptiness," Ven. Yinshun’s "Humanistic Buddhism" placed importance on "human duty" rather than "animal rights", suggesting that in pursuit of the value of human goodness animal protection is compulsory. Lastly, I argued that Ven. Yinshun’s "Humanistic Buddhism" on animal protection indeed had a higher goal and concern, including care of suffering, nurture of compassion, encouragement of spiritual life and even realization of nirvana.
