The works of Ādi Śaṅkarācārya

Bṛhadāraṇyakopaniṣadbhāṣyam

Verse 371

होमं कुर्यादनुष्टुभार्चनं तदेतद्रक्षोघ्नं मृत्यु-तारकं गुरुतो लब्धं कण्ठे बाहौ शिखायांवा बध्नीत सप्तद्वीपवती भूमिर्दक्षिणार्थंनावकल्पते तस्माच्छ्रद्धया यां कांचिद्द-द्यात्सा दक्षिणा भवति ॥ २ ॥

In plain words

The instruction turns practical: chant the Anuṣṭubh in worship, offer the fire-oblation with it. Once a teacher has given you this, wear it -- at the throat, on the arm, or tied into the topknot -- and it will guard against harm and carry you past death itself. And about payment for a teaching like this: not even the whole earth, all seven continents of it, would be enough. So the text settles the matter simply -- give whatever you can, however small, but give it with real faith. That, and nothing more, is what counts as the proper gift.

Close to the Sanskrit

...through worship with the Anuṣṭubh, one should perform the fire-oblation with the Anuṣṭubh. This, obtained from a teacher, destroys evil spirits and carries [one] across death; one should bind it on the neck, on the arm, or in the topknot. Even the earth possessing the seven continents is not sufficient as a ritual gift for it; therefore, whatever [gift], however small, one gives with faith, that becomes the ritual gift. || 2 ||
