। ॥ ५३९ ॥
In plain words
"I am one thing, and happiness is something else" — once a person without discrimination has settled that in his mind, he spends his whole life straining after happiness outside himself. That is exactly what happens; there is no doubt about it.
Close to the Sanskrit
"The Self is one thing and happiness another" — having settled it thus, the undiscerning man strives for external happiness; this is true indeed, there is no doubt.
