Did the Buddha work with teachers from other spiritual traditions? Within the Pali canon the Buddha often vigorously debates with Brahmin priests. However in the Buddha's time there were a lot of other spiritual traditions too. Did the Buddha have more cordial relationships with teachers of other faiths too? Are there examples of him working together with spiritual teachers of other traditions? I'm specifically asking about his teaching after he became enlightened. I know he studied with several teachers before that point.
Jatila brothers who had thousand disciples had some relationship with Lord Buddha. But they had evil intentions inside. But Lord Buddha knew their evil intentions. But they soon realized Lord Buddha was superior. Jatila brothers along with their thousand disciples became arhats after listening to Aditta Pariyaya Sutta. You can read the story here. I am unable to recall some other instances where other teachers had good relationships with Lord Buddha, but there must have been.
