Bhumicalasutta 16.1

16.1

Puna caparaṃ, ānanda, yadā bodhisatto tusitā kāyā cavitvā sato sampajāno mātukucchiṃ okkamati, tadāyaṃ pathavī kampati saṅkampati sampakampati sampavedhati.

Furthermore, when the being intent on awakening passes away from the host of joyful gods, he’s conceived in his mother’s womb, mindful and aware. Then the earth shakes and rocks and trembles.
