Parāvasu and Arvāvasu
उग्र॑ं तप: समास्थाय दिवाकरमथाश्रित: । रहस्यवेदं कृतवान् सूर्यस्य द्विजसत्तम:
ugraṁ tapaḥ samāsthāya divākaram athāśritaḥ | rahasyavedaṁ kṛtavān sūryasya dvijasattamaḥ ||
Ang pinakadakila sa mga “dalawang-beses na isinilang” ay nagsagawa ng mabagsik na pag-aayuno at pagdurusa, at kumupkop sa Araw (Divākara). Sa pamamagitan ng disiplinadong tapas at debosyon, natamo niya ang lihim na kaalaman ng Sūrya—isang esoterikong aral ng Veda.
लोगश उवाच
Intense self-discipline (tapas) combined with taking refuge in a worthy divine source (here, Sūrya) is presented as a means to gain higher, guarded knowledge; spiritual attainments are shown as fruits of sustained austerity and proper orientation of devotion.
The speaker states that a foremost Brahmin-sage performed severe austerities, sought the Sun as his refuge, and thereby acquired the Sun’s ‘rahasya-veda’—a secret or esoteric Vedic teaching—indicating a transmission of special knowledge earned through tapas.
