अङ्गुष्ठमात्रः पुरुषो मध्य आत्मनि तिष्ठति ।
ईशानं भूतभव्यस्य न ततो विजुगुप्सते । एतद्वै तत् ॥ १२ ॥
aṅguṣṭhamātraḥ puruṣo madhya ātmani tiṣṭhati |
īśānaṃ bhūtabhavyasya na tato vijugupsate | etadvai tat || 12 ||
The Puruṣa (Self), of the size of a thumb, resides in the middle of the body as the lord of the past and the future, (he who knows Him) fears no more. This verily is That.
