The 1970 Triple Platform Ordination at Linji Huguo Chan Temple in Taipei City marked the first Dual Ordination in Taiwanese history. It was also the first time in Taiwan that a bhikshuni lectured the Bhiksuni Pratimoksa of Dharmaguptaka to female preceptees in Taiwanese during the entire ordination session. Therefore, this incident holds significant historical importance. The female preceptor, Venerable Tianyi, had a Batchelor’s degree from Japan, led four temples in her lifetime, participated in over 10 ordinations, and lectured on the Bhiksuni Pratimoksa for four times, nurturing numerous monastics. Thus, her perspectives on the Vinaya need to be investigated. This study focuses on exploring the characteristics and core aspects of Venerable Tianyi’s explanations on Vinaya. We collected recordings of the 1970 Triple Platform Ordination at Linji Huguo Chan Temple, analyzed the lecture contents, and conducted interviews. The analysis results revealed the following characteristics: 1. Taiwanese was employed to recite the rules of Vinaya one by one and to give simple explanations. 2. The origin and meaning of establishing the Vinya were interpreted, and the means to learn the Vinaya was demonstrated. 3. Metaphors were skillfully used, and real-life examples were incorporated to address the practical application of the Vinya. 4. The Bhiksunis were led to become self-aware and subsequently to enlighten others. The core aspects of the Vinaya emphasized by Venerable Tianyi include the followings. 1. Eliminating the habits and problems of women. 2. Emphasizing the deportment of monastics. 3. Being aware of boundaries between bhiksunis and laypeople during daily interactions. 4. Handling monastic possessions with a clear understanding of cause and effect. 5. Valuing mutual respect and care in communal living. 6. Adhering to principles of interaction between the sanghas of bhiksuni and bhikkhu. Taiwanese Bhiksunis should continue to emphasize Vinaya, unite the female monastic community, and engage with the international community. In the future, we should preserve valuable historical materials, utilize technology to restore and preserve historical data in order to bear witness of the historical development of Buddhism in Taiwan.
