Śatapatha Brāhmaṇa ("of a hundred paths") 11.2.7.29

11.2.7.29

pratiṣṭhā śamyorvākaḥ sa yo ha vai pratiṣṭhā śamyorvāk iti vedāva ha pratiṣṭhāṃ runddhe'tho yatkiṃ ca pratiṣṭhayā jayyaṃ sarvaṃ haiva tajjayati gacati pratiṣṭhām

The Samyorvâka is the resting-place; and, verily, whosoever knows the Samyuvâka to be the resting-place secures for himself a resting-place; and whatever is to be gained by a resting-place all that he now gains: he reaches a resting-place.
