Verse
Four short verses that get quoted on their own, each one exact: from the Gita, an Upaniṣad, and one that opens a teacher's blessing before study begins.
Ślokas travel by memory, often stripped from the fuller text around them — a single line doing the work of the whole. Reciting one is common at the start of a class, a prayer, or a difficult decision; the four here are exact, not paraphrased, and each names where it comes from.
