Engage your mind in thinking of Me, become My devotee, offer obeisances to Me, and worship Me. Being completely absorbed in Me, surely you will come to Me. I promise you this because you are My very dear friend."
While this verse does not directly address dealing with deceit, it emphasizes staying true to one's devotion and principles. In dealing with lies or dishonesty, Krishna's teachings generally encourage maintaining one's integrity and righteousness regardless of the actions of others.
