This paper explores the construction of regulations and the context of operation of a bhiksuni Bodhisattva Sangha, which applies Buddha’s “ten principles of making precepts” as the legal basis for making regulations. Meanwhile, they are also the source and guidelines for facing the future changes because of time, space, and different conditions; their ultimate goal is to make the proper dharma abide long. Besides following Buddha's precepts, it also inherits the organization and operation of monastic rules for Buddhists, Buddhist rituals, and regulations for living together, in accordance with the spirit of altruism in Mahayana bodhisattva, and carries out a system adaptive to the times and the truth for Buddhism. It also makes a reform of some institutional practices and ideologies which violate the spirit of Buddhism and precepts and hinder the progress of Buddhism, such as the Eight Garudhammas (Eight Special Rules), hereditary system, repentance rites, authoritativeness of teachers, and the concept of class. The peace and purity of a Sangha comes from a regulated life follow according to the precepts in voting of meeting (karma). So the Sangha is not afraid of having argument, there is a crisis management mechanism to eradicate it, which means according to the seven laws to eliminate argument (Adhikarana-Samatha), a Sangha could go back to a reconciled one. After entering a Sangha, the first laws for a person to learn are face to face evidence (saṃmukha-vinaya) and remonstrance in return. These two laws are the treasures to maintain Sangh’s peace and purity, which have a significant effectiveness of developing the bright side of a person and helping people form a candid, compassionate, and courageous character. With examples in real life, the author tries to provide a complete and clear presentation of the context of making all kinds of regulation in a Sangha and its purpose to achieve.
