Bhagavad Gita, Chapter 7, Verse 15

They do not devote themselves to Me, the evil-doers, the deluded, the lowest of men, deprived of discrimination by Mâyâ, and following the way of the Asuras.

Not surrendering isn't described as one single problem, it actually comes from a few genuinely different real causes.

This breaks down resistance into distinct categories, lack of knowledge, plain laziness, real confusion, or something more actively opposed. Naming these separately matters, because each one likely needs a different real response.
