Shloka 16

ज्ञान त्वेव परं विद्य: संन्यासं तप उत्तमम्‌ | यस्तु वेद निराबाधं ज्ञानतत्त्वं विनिश्चयात्‌ । सर्वभूतस्थमात्मानं स सर्वगतिरिष्यते,हम ज्ञानको ही परब्रह्म और संन्यासको उत्तम तप जानते हैं। जो अबाधित ज्ञानतत्त्वको निश्चयपूर्वक जानकर अपनेको सब प्राणियोंके भीतर स्थित देखता है, वह सर्वगति (सर्वव्यापक) माना जाता है

jñānaṃ tveva paraṃ vidyāḥ saṃnyāsaṃ tapa uttamam | yastu veda nirābādhaṃ jñānatattvaṃ viniścayāt | sarvabhūtastham ātmānaṃ sa sarvagatir iṣyate ||

Vāyu said: “Know that true knowledge is the highest attainment, and renunciation is the supreme austerity. Whoever, with firm certainty, understands the unobstructed principle of knowledge and sees the Self as abiding within all beings—such a person is regarded as ‘all-going,’ one whose realization is universal and unconfined.”

Educational Q&A

The verse elevates two complementary disciplines: (1) jñāna—clear realization of truth—as the highest attainment, and (2) saṃnyāsa—inner renunciation—as the greatest austerity. The mark of genuine knowledge is seeing the same Self present in all beings, which makes one’s vision and conduct universal rather than narrow or self-centered.

Vāyudeva is speaking as an instructor, defining what counts as the highest wisdom and the highest tapas. He characterizes the realized person as one who has decisively grasped the unobstructed truth of knowledge and perceives the Self within all creatures, thereby being regarded as ‘sarvagati’—unrestricted and universal in spiritual standpoint.
