Sanskrit
अवजानन्ति मां मूढा मानुषीं तनुमाश्रितम् । परं भावमजानन्तो मम भूतमहेश्वरम् ॥
avajānanti māṃ mūḍhā mānuṣīṃ tanum āśritam paraṃ bhāvam ajānanto mama bhūtamaheśvaram
Translation
The foolish disregard Me, when clad in human semblance, ignorant of My supreme nature, the great Lord of beings;
Annie Besant · The Bhagavad-Gita, translated by Annie Besant (4th ed., 1922) — Wikisource · Public Domain
Explanation
The tone shifts from cosmology to critique: those who see Krishna’s human form and conclude that’s the whole of him are called “foolish” (mūḍhāḥ), ignorant of the “supreme nature” just laid out in verses 4-10. This sets up the contrast verse 13 completes — the mūḍhāḥ here against the mahātmānaḥ there, same divine reality, opposite responses.
