Path of Vision, the Path of Cultivation, and the Path of the Adept”. However, whether it is a fixed module still requires more studies. Besides that, regarding the prior studies on the Four Immeasurables they focus more on the topic of the Immeasurable liberation, only few discussions on the path of liberation. Therefore, I try to clarify the relationship between the Four Immeasurables and the Path of Liberation of “Sarvāstivāda School”. Among the “Sarvāstivāda School” abhidharma literature texts, the three Chinese translation of Vibhāṣā compendia bear rich explanations of the Four Immeasurable comparing to others. Moreover, among the three translations Abhidharma Mahāvibhāṣa Sāstra has the most complete discussion on the Four Immeasurable. Furthermore, previous studies do not consult the others two Abhidharma Mahāvibhāṣa Sāstra which are equally important. These are reasons why I choose the three Chinese translated texts as my primary source. Finally, some conclusions are drawn especially on relation to the main points discussed in the fourth part of the essay. I found that the Four Immeasurables are Categorized as a “part of the Aid of Merit”, but also are endowed with other function, such as extent the life in the Path of the Adept. Moreover, the Aids to Merit and the Aids to Liberation could simultaneously accomplish, and so far the Path of Liberation had their fixed sequence.
