Mahāpadānasutta

Suttapiṭaka · Dīghanikāya · Mahāvagga · Vol. 10 · Section 23

[23] Bhikkhus, this is the natural order (dhammatā): when the Bodhisatta emerges from his mother's womb, before the Bodhisatta has reached the ground, four young deities (devaputtā) receive him and set him before his mother, saying, 'Rejoice, O Queen! A son of great majesty has been born to you.' This is the natural order in this case.
