三彌勒經疏 1.168

1.168

問：准餘宗，菩薩生時聲唯至欲界他化自在天，成佛道時聲至色界究竟，轉法輪時聲至梵天。云何今此經但言成道聲至梵天？答，彼意言者，菩薩生時受欲界身，故唯至第六天。成道時作三界主，故逕色究竟。轉法輪時由大梵請，故至梵世。然今此經意，二定以上無自地語聲，故順言至梵世耳也。

Question: According to other traditions, when a bodhisattva is born, the sound reaches only up to the Paranirmitavaśavartin heaven of the desire realm; when he attains the Buddha-way, the sound reaches the Akaniṣṭha heaven of the form realm; and when he turns the wheel of the Dharma, the sound reaches the Brahmā heavens. Why does this sūtra only say that at the attainment of awakening the sound reached the Brahmā heavens? Answer: Their intended meaning is that when a bodhisattva is born, he assumes a body of the desire realm, so it reaches only up to the sixth heaven. When he attains awakening, he becomes the lord of the three realms, so it passes directly to Akaniṣṭha. When he turns the wheel of the Dharma, it is due to the request of Mahābrahmā, so it reaches the realm of Brahmā. However, the intent of this sūtra is that above the second dhyāna there is no vocal sound of their own stage; therefore, conforming [to this principle], it merely states that it reached the realm of Brahmā.
