Sanskrit
ये त्वेतदभ्यसूयन्तो नानुतिष्ठन्ति मे मतम् । सर्वज्ञानविमूढांस्तान्विद्धि नष्टानचेतसः ॥
ye tv etad abhyasūyanto nānutiṣṭhanti me matam sarvajñānavimūḍhāṃs tān viddhi naṣṭān acetasaḥ
Translation
Who carp at My teaching and act not thereon, senseless, deluded in all knowledge, know thou these mindless ones as fated to be destroyed.
Annie Besant · The Bhagavad-Gita, translated by Annie Besant (4th ed., 1922) — Wikisource · Public Domain
Explanation
The rhetoric turns sharply harsher than anything earlier in the chapter — “fated to be destroyed” is a much stronger consequence than the patient, non-unsettling tone of verses 26 and 29 toward the merely ignorant. The distinction being drawn is between people who simply haven’t yet understood, treated with restraint, and people who actively reject the teaching out of contempt, which the text treats as a different and graver failure.
