Sanskrit
तद्विद्धि प्रणिपातेन परिप्रश्नेन सेवया । उपदेक्ष्यन्ति ते ज्ञानं ज्ञानिनस्तत्त्वदर्शिनः ॥
tad viddhi praṇipātena paripraśnena sevayā upadekṣyanti te jñānaṃ jñāninas tattva-darśinaḥ
Translation
Learn thou this by discipleship, by investigation, and by service. The wise, the seers of the essence of things, will instruct thee in wisdom.
Annie Besant · The Bhagavad-Gita, translated by Annie Besant (4th ed., 1922) — Wikisource · Public Domain
Explanation
Having declared knowledge supreme, the text immediately specifies how it’s obtained: not through solitary insight but through praṇipāta (submitting to a teacher), paripraśna (asking real questions, not idle ones), and sevā (service) — offered to those who are tattva-darśinaḥ, seers who have directly perceived reality rather than merely reasoned their way to a position on it. It reads as a corrective against taking verse 33 as license for armchair philosophizing: the sacrifice of wisdom still comes with a discipline and a lineage attached to it.
