The Katha Upanishad with Shankara’s Commentary
महतः परमव्यक्तमव्यक्तात्पुरुषः परः ।
पुरुषान्न परं किंचित्सा काष्ठा सा परा गतिः ॥ ११ ॥
mahataḥ paramavyaktamavyaktātpuruṣaḥ paraḥ |
puruṣānna paraṃ kiṃcitsā kāṣṭhā sā parā gatiḥ || 11 ||
Beyond the great Ātman is the Unmanifested; beyond the Unmanifested is the Puruṣa (the Cosmic Soul); beyond the Puruṣa there is nothing. That is the end that is the final goal.
