Bhagavad Gita Chapter 7.24
avyaktaḿ vyaktim āpannaḿ
manyante mām abuddhayaḥ
paraḿ bhāvam ajānanto
mamāvyayam anuttamam
Translation
Unintelligent men, who do not know Me perfectly, think that I, the Supreme Personality of Godhead, Krishna, was impersonal before and have now assumed this personality. Due to their small knowledge, they do not know My higher nature, which is imperishable and supreme.
