The Yoga of the Imperishable Brahman
सुखमात्यन्तिकं यत्तद् बुद्धिग्राह्म॒मतीन्द्रियम् । वेत्ति यत्र न चैवायं स्थितश्षलति तत्त्वत:
sukham ātyantikaṃ yat tad buddhi-grāhyam atīndriyam | vetti yatra na caivāyaṃ sthitaś calati tattvataḥ ||
जो सुख अत्यन्तिक है—जो शुद्ध बुद्धि से ग्रहण होता है और इन्द्रियों से परे है—जिसमें (आत्मतत्त्व को) जाना जाता है, और जिसमें स्थित होकर यह पुरुष तत्त्व से विचलित नहीं होता।
अर्जुन उवाच
