त्रिभिर्गुणमयैर्भावैरेभिः सर्वमिदं जगत्। मोहितं नाभिजानाति मामेभ्यः परमव्ययम् ॥

tribhir guṇa-mayair bhāvair ebhiḥ sarvam idaṁ jagat mohitaṁ nābhijānāti māmebhyaḥ param avyayam

All this world, deluded by these natures made by the three qualities, knoweth not Me, above these, imperishable.

In plain words: Krishna says the whole world is fooled by these three moods of nature. Because of this, people do not recognize him, who is beyond them and never dies.
