The Self shines in the Heart
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 Purusha, of the size of a thumb, dwells in the body. He is the Lord of the past and the future. After knowing Him, one does not conceal oneself any more. This, verily, is That.
Swami Vivekananda Says —
(Verses 12 and 13)
…know it for certain that there is no greater Tirtha (holy spot) than the body of man. Nowhere else is the Atman so manifest as here. That car of Jagannatha that you see is but a concrete symbol of this corporeal car. You have to behold the Atman in this car of the body. Haven’t you read “आत्मानं रथिनं विद्धि — Know the Atman to be seated on the chariot” etc., “मध्ये वामनमासीनं विश्वे देवा उपासते — All the gods worship the Vâmana (the Supreme Being in a diminutive form) seated in the interior of the body”? The sight of the Atman is the real vision of Jagannatha. And the statement “रथे च वामनं दृष्टा पुनर्जन्म न विद्यते — Seeing the Vâmana on the car, one is no more subject to rebirth”, means that if you can visualise the Atman which is within you, and disregarding which you are always identifying yourself with this curious mass of matter, this body of yours — if you can see that, then there is no more rebirth for you.[Source]
Oh, One that cannot be confined or described! One that can be perceived in our heart of hearts! One beyond all compare, beyond limit, unchangeable like the blue sky! Oh, learn the All, holy one I Seek for nothing else![Source]
