Buddhacarita by Ven Asvaghosa - Ancient Buddhist Texts

Buddha-carita, or Life of Buddha - 164
27. Such were the troops of demons who encircled the root of the
Bodhi tree on every side, eager to seize it and to destroy it, awaiting
the command of their lord.
28. Beholding in the first half of the night that battle of Māra and the
bull of the Śākya race, the heavens did not shine and the earth shook
and the (ten) regions of space flashed flame and roared.
29. A wind of intense violence blew in all directions, the stars did not
shine, the moon gave no light, and a deeper darkness of night spread
around, and all the oceans were agitated.
30. The mountain deities and the Nāgas who honoured the Law,
indignant at the attack on the saint, rolling their eyes in anger against
Māra, heaved deep sighs and opened their mouths wide.
31. But the god-sages, the Śuddhādhivāsas, being as it were absorbed
in the perfect accomplishment of the good Law, felt only a pity for
Māra in their minds and through their absolute passionlessness were
unruffled by anger.
32. When they saw the foot of the Bodhi tree crowded with that host
of Māra, intent on doing harm, – the sky was filled with the cry
raised by all the virtuous beings who desired the world’s liberation.
33. But the great sage having beheld that army of Māra thus engaged
in an attack on the knower of the Law, remained untroubled and
suffered no perturbation, like a lion seated in the midst of oxen.
