In this paper, the author, taking Buddha-name chanting Samadhi for example, elaborates the meaning and characteristics of Buddhist practice on the principles of meditation and wisdom, and the approach to practice, to discover the deep meaning of the Approach to Achieve Araṇā-samādhi with All Phenomena. Those who take the path of Mahayana Bodhisattva generally regards Prajnaparamita (wisdom) as Mother of the Six Paramitas, but Hui-si alone places “Meditaion Paramita” at an important central place. According to Hui-si, the way to Buddhahood begins with Meditation Paramita; after the Samadhi is attained, the practitioners then have the power to achieve their potentials of sensual organs and wisdom, and can even complete the merits of Buddhahood. Further, the state of the Buddha-name Chanting Samadhi that this paper states, is precisely the incredible one that is attained by developing the observing wisdom of the emptiness in nature, with the Samadhi brought by Meditation (Dhyāna pāramitā) plus the power of Buddha and one’s merits. The familiarity of Buddha-name chanting could be gradually bred as the force of meditation and wisdom has progressed. Therein, one can witness “immeasurable Buddhas being present in front,” and attains Pratyutpanna Samadhi, the profound and great wisdom of emptiness in nature. One can perceive and manifest the true meaning of Buddha-name chanting—dependent origination, the emptiness in nature, and the middle path. In practice, one can also confirm the highest truth of “the Approach to Achieve Araṇā-samādhi with All Phenomena.”
