to escape from the abyss of suffering / to shed off a wretched plight
苦海无边,回头是岸
kǔ hǎi wú biān , huí tóu shì àn
The sea of bitterness has no bounds, turn your head to see the shore (idiom). Only Buddhist enlightenment can allow one to shed off the abyss of worldly suffering. / Repent and ye shall be saved!
