Original Sanskrit · श्रीभगवान्
सुखमात्यन्तिकं यत् तद् बुद्धिग्राह्यमतीन्द्रियम्
वेत्ति यत्र न चैवायं स्थितश्चलति तत्त्वतः
॥ 6.21 ॥
sukhamātyantikaṃ yat tad buddhigrāhyamatīndriyam
vetti yatra na caivāyaṃ sthitaścalati tattvataḥ
Translation
"In which (the yogi) knows that supreme happiness which is beyond the senses and grasped by the intellect alone; and established in which, one never strays from one's truth — (continued in 6.22–6.23)"
Interpretation
Shankaracharya. Ātyantikam atyantam eva bhavati ity ātyantikam anantam ity arthaḥ — that which is "beyond the end", that is, endless; buddhyaiva indriya-nirapekṣayā gṛhyate iti buddhi-grāhyam — grasped by the intellect alone, without depending on the senses; atīndriyam … aviṣaya-janitam — not born of objects. And na … calati tattvataḥ tattva-svarūpāt na pracyavate — one does not fall away from the nature of reality.
Acharya Ramanuja. Atīndriyam ātma-buddhy-eka-grāhyam ātyantikaṃ sukham — a supreme happiness beyond the senses, grasped only by the intellect directed to the self; yatra ca yoge sthitaḥ sukhātirekeṇa tattvataḥ tad-bhāvāt na calati — the yoga in which, once established, one does not stray from that state because of the abundance of happiness.
The difference (subtle): Ramanuja's argument is psychological too — the yogi does not stray because this happiness is so abundant that nothing else pulls.
