▸Bhagavadgītābhāṣyam
यस्मादेवं तस्मात् —
तपस्विभ्यः अधिकः योगी, ज्ञानिभ्योऽपि ज्ञानमत्र शास्त्रार्थपाण्डित्यम् , तद्वद्भ्योऽपि मतः ज्ञातः अधिकः श्रेष्ठः इति । कर्मिभ्यः, अग्निहोत्रादि कर्म, तद्वद्भ्यः अधिकः योगी विशिष्टः यस्मात् तस्मात् योगी भव अर्जुन ॥ ४६ ॥
In plain words
Since this is how it stands, therefore —
The yogī stands above those who practise austerity. He stands above the knowers as well — and 'knowledge' here means mastery of what the scriptures mean, scholarship; above even those who have that. 'Held to be' means known to be; 'greater' means finest of all. And above the ritualists — the agnihotra and rites like it are the 'action' meant here — above those who perform them the yogī stands, the one marked out. Since that is how it stands: be a yogī, Arjuna.
Close to the Sanskrit
Since (it is) thus, therefore —
Than ascetics the yogī is greater; than the knowers also — 'knowledge' here is scholarly mastery of the purport of the scriptures — than those possessing that also, 'mataḥ' means 'known', 'adhikaḥ' means 'foremost'; thus. Than the ritualists — the agnihotra and the like is 'karma' — than those possessing that the yogī is greater, distinguished. Since it is so, therefore be a yogī, Arjuna.
