Uv33:74
divā tapati hādityo rātrāv ābhāti candramāḥ |
saṃnaddhaḥ kṣatriyas tapati dhyāyī tapati brāhmaṇaḥ |
atha nityam ahorātraṃ buddhas tapati tejasā ||

Uv 33.74
By day the sun blazes; at night the moon shines;
accoutered in armor, the kṣatriya blazes; the meditating brahmin blazes;
yet constantly, day and night, the Buddha blazes with splendor.
