Perhaps in modern language, the way I see a worldly being entrapped in sansara is akin to a catch-22 situation. The wordly being does not know that he is in such a predicament, especially those who are indulging themselves heavily in sensual pleasures. They don’t know that sensual pleasures can only be realised if and only if the premise is dukkha. If they don’t go looking for dukkha, how do they enjoy the sensual pleasures through the temporary relief from dukkha? How fortunate we are to have the opportunity to learn the method Lord Buddha discovered to rig the system! Imagine if the Buddha did not discover the method to rig sansara, we are all screwed!
A sotapanna has clearly seen the priceless value in this rigging method and places unshakable faith in using this method to get out of sansara. Whereas the worldly being cannot leave the prison they entrapped themselves in because they themselves are the prison!
