ईशानो भूतभव्यस्य स एवाद्य स उ श्वः । एतद्वै तत् ॥ १३ ॥
aṅguṣṭhamātraḥ puruṣo jyotirivādhūmakaḥ |
īśāno bhūtabhavyasya sa evādya sa u śvaḥ | etadvai tat || 13 ||
That Puruṣa, of the size of a thumb, is like a light without smoke, lord of the past and the future. He is the same today and tomorrow. This verily is That.
