The Upaniṣads — the philosophical core of the Vedic tradition, revealing the nature of Brahman, the Ātman, knowledge, action and liberation. The ten principal Upaniṣads together with select minor Vaiṣṇava Upaniṣads.
A condensed retelling of the Maitrāyaṇī, with a different ending: the same king, the same question of disgust at the body — but the book ends not with an abstraction, but with the name Puruṣottama, "the Supreme Spirit."
