At Uruvelā (1st) 8.1

8.1

Atha kho, bhikkhave, brahmā sahampati mama cetasā cetoparivitakkamaññāya—seyyathāpi nāma balavā puriso samiñjitaṃ vā bāhaṃ pasāreyya, pasāritaṃ vā bāhaṃ samiñjeyya; evamevaṃ—brahmaloke antarahito mama purato pāturahosi.

And then the divinity Sahampati, knowing my train of thought, vanished from the realm of divinity and appeared in front of me, as easily as a strong man would extend or contract his arm.
