Question: Since it is said to be nowhere not present, Buddhahood could also be attained in the first, second, or third dhyānas; why must it be specifically in the Akaniṣṭha Heaven? Answer: There are two meanings to this: first, the Avataṃsaka clarifies that the position of a bodhisattva on the tenth ground is lodged in the fourth dhyāna, and it is right there that they manifest the attainment of Buddhahood; second, when on the verge of attaining Buddhahood, the vajropamasamādhi entered must rely on dhyāna accompanied by equanimity.
