Kaṭha Upaniṣad

The Kaṭha Upaniṣad is attached to the Kaṭha school of the Kṛṣṇa Yajurveda and is one of the most celebrated of the principal Upaniṣads. It narrates the story of the young boy Nachiketas who visits the realm of Death (Yama) to learn the secret of what happens after death.

Overview

The text is divided into two chapters (adhyāyas), each divided into three sections (vallīs). The first adhyāya presents the dialogue between Nachiketas and Yama, while the second contains philosophical teachings on the nature of the Self and the means to liberation.

Content

The story begins with Nachiketas being sent to the realm of Death by his father. Yama offers him three boons, and for the third, Nachiketas asks about the secret of death. After testing the boy’s resolve, Yama teaches him that the Self (Ātman) is eternal, unborn, and indestructible. The text famously describes the Self as smaller than the smallest and greater than the greatest.

Significance

The Kaṭha Upaniṣad is one of the earliest philosophical texts to articulate the concept of Ātman (Self) and its identity with Brahman. It introduces important metaphors including the chariot analogy for the body and mind, and the comparison of the Self to a lamp. The text has profoundly influenced Hindu, Buddhist, and Jain philosophy.
