ahameko'vatīryaitānhaniṣyāmi bhuvo bharān | svadharmaśapathā vo vai saṃti cejjanma prāpsyatha
唯我将亲自降世，诛灭这压在大地上的重担。若你们以自身之法（达摩）所立誓愿仍然坚固不移，那么你们必将确实得生于人间。
Unclear from snippet (dialogue within Kaumārikākhaṇḍa; speaker appears to be a deity/leader making a vow of descent)
Scene: A heroic figure declares: ‘I alone will descend’; his posture is martial and protective; behind him, celestial beings listen as if receiving a call to incarnate based on their dharma-oaths.
FAQs
