Gita 3.32

Gita 3.32

Ye, tu, etat’, abhyasooyantH, na, anutishthanti, me, matam’,
Sarvgyanvimoodan’, taan’, viddhi, nashtaan’, achetasH ||32||

Translation: (Tu) but (ye) those who (abhyasooyantH) while blaming/attributing fault (me) mine (etat’) this (matam’) opinion i.e. principle (na, anutishthanti) do not follow (taan’) those (achetasH) fools; you (sarvgyanvimoodan’) enamoured in all knowledge and (nashtaan’) destroyed only (viddhi) consider. (32)

Bhagavad Gita Chapter 3 Verse 32

But those who blame and do not follow this opinion i.e. principle of mine, consider those fools to be enamoured in all knowledge and destroyed only.

Important: In Gita Chapter 3 Verse 25 to 29, has given a detailed account of the opinion i.e. principle told by himself. He has expressed his opinion in Gita Chapter 3 Verse 25 to 29 that if an educated person is doing sadhna abandoning the injunctions of the scriptures and he finds an uneducated person doing scripture-based sadhna, then he should not confuse him, rather, should himself also accept his way of worship. After taking initiation from a Complete Saint, should get his welfare done. This evidence is also in Gita Chapter 13 Verse 11.
