BG 7.13-15
All this world, deluded by these natures made by the three qualities, knoweth not Me, above these, imperishable. This divine illusion of Mine, caused by the qualities, is hard to pierce; they who come to Me, they cross over this illusion. The evil-doing, the deluded, the vilest men, they come not to Me, they whose wisdom is destroyed by illusion, who have embraced the nature of demons.
