Thanks so much @faujidoc1! Unfortunately that isn’t it.
I’ll read through the rest of that sutta, to see if it was there.
Originally it came up in a thread, in the context of practicing alone and ‘manifesting’ a being/external ‘entity’ to help discuss/get deeper, into seeing things as they are, dispel delusion, etc. ie ‘create’ a wise kalyanamitta, when none are available
Someone replied that the Buddha had done something similar calling up or manifesting a Deva for this kind of role, and gave a sutta reference. From memory, i thought it was during his quest for Awakening…
Thanks for you help. Much appreciated
