Bhashya
यो वै भूमा महत् निरतिशयं बह्विति पर्यायाः, तत्सुखम् ।ततोऽर्वाक्सातिशयत्वादल्पम् ।अतस्तस्मिन्नल्पे सुखं नास्ति, अल्पस्याधिकतृष्णाहेतुत्वात् ।तृष्णा च दुःखबीजम् ।न हि दुःखबीजं सुखं दृष्टं ज्वरादि लोके ।तस्माद्युक्तं नाल्पे सुखमस्तीति ।अतो भूमैव सुखम् ।तृष्णादिदुःखबीजत्वासंभवाद्भूम्नः ॥
In plain words
That which is the Infinite—great, unsurpassed, abundant, these are its synonyms—that is joy. Anything short of that is finite because it can be surpassed. Therefore, there is no real joy in the finite, for petty things only breed greater cravings. Craving is the seed of all suffering; in everyday life, what breeds suffering—like a fever—is never experienced as happiness. Thus it is entirely fitting to say that there is no joy in the small. Consequently, the Infinite alone is joy, since the Infinite can never be the source of craving and misery.
Close to the Sanskrit
What indeed is the Infinite—great, unexcelled, abundant, these are synonyms—that is happiness. Inferior to that, because it can be surpassed, is the small. Hence in that small there is no happiness, because the small causes greater craving. And craving is the seed of misery. For the seed of misery is not seen as happiness in the world, like fever and the rest. Therefore it is proper that there is no happiness in the small. Hence the Infinite alone is happiness, because the impossibility of the Infinite being the seed of craving and other sorrows.
