In general, the chapter on ten stages or bhūmis (Shidi Pin十地)is considered the core of the Hua-Yan Sūtra. The content describes the practice process of Bodhisattvas. This thesis investigates into Ming-di (明地) which is the third of the ten stages. The content describes the theme of seeking Dharma and practiced of meditation. The description of the Scripture is not as inconceivable and marvelous as we imagined. On the contrary, the text is similar to the learning process of Four Dhyāna and Eight Attainment meditation described in the Agama《阿含經》. If we were to look at the whole structure of Hua-Yan Sūtra, it includes the content of faith, understanding, practice, and realization (信、解、行、證). In terms of the sequence of levels of practices, it includes ten faith (十信), ten abodes (十住), ten practices (十行), ten dedications of merit (十迴向), ten stages (十地), virtual enlightenment (等覺), and wonderful enlightenment (妙覺). The first few chapters of Hua-Yan Sūtra consist of characteristics peculiar to Buddha Dharma (不共法) it presented the marvelous Sea of Buddha-fruition of Buddha grounds or bhūmis. However, the description in the chapter of ten stages (Shidi pin) is a shared common Dharma with the teaching of human and celestial beings as well as the three vehicles; logically the earlier chapters should be easier than the later, but it is the opposite in the Scripture. This thesis used Scriptures and texts from Hua-Yan School as a based, through Doctrinal classification of Hua-Yan and the ideology of Pretext of rank (寄位思想teaching according to the level of the practice of the Bodhisattvas) to clarify the above problem, and go one step further to understand that in fact there is no differentiation in term of Stages in Hua-Yan One Vehicle Separate Teaching, once A position is attained, it is identical to all positions; All positions identical to one position. On the one hand, although I used the approach of sequence and differentiation to illustrate, on the other hand it does not hinder the essence of Perfect interpenetration without obstruction of Hua Yan. In this way, I will not interpreting only the apparent meaning of the Sūtra but able to extend the view to all different stages and even the whole Hua- Yan Sūtra.
