“All Buddhas in the past, the Buddhas of the future, and the Buddha at present—destroyer of the sorrows of many—
respecting the true teaching they did live, they do live, and they also will live. This is the nature of the Buddhas.
Therefore someone who desires self-knowledge, and aspires to greatness themselves, should respect the true teaching, remembering the instructions of the Buddhas.”
Linked Discourses 6.3 1. The Appeal With Brahmadeva
So I have heard. At one time the Buddha was staying near Sāvatthī in Jeta’s Grove, Anāthapiṇḍika’s monastery. Now at that time a certain brahmin lady had a son named Brahmadeva, who had gone forth from the lay life to homelessness in the presence of the Buddha.
Then Venerable Brahmadeva, living alone, withdrawn, diligent, keen, and resolute, soon realized the supreme culmination of the spiritual path in this very life. He lived having achieved with his own insight the goal for which gentlemen rightly go forth from the lay life to homelessness. He understood: “Rebirth is ended; the spiritual journey has been completed; what had to be done has been done; there is nothing further for this place.” And Venerable Brahmadeva became one of the perfected.
