The works of Ādi Śaṅkarācārya

Viṣṇusahasranāmastotram

Verse 560

दक्षिणाहृदयो योगी महासत्रमयो महान् ।उपाकर्मोष्ठरुचकः प्रवर्ग्यावर्तभूषणः ॥

In plain words

The priest's gift is his heart. He is the Yogin. The great satra is what he is made of, and he is vast. The opening rite is the jewel at his lips; the pravargya is the curl of hair he wears as ornament.

Close to the Sanskrit

He whose heart is the dakṣiṇā, the Yogin, he who consists of the great satra, the Great One; he whose lip-ornament is the upākarman rite, he whose adornment is the whorl of the pravargya.
