The sea of ??suffering is boundless, and when you turn back you will find a shore
The sea of ??suffering is boundless, and when you turn back you will find a shore: It means that the world is like a sea of ??suffering, boundless, and only through enlightenment can one achieve transcendence. It also serves as a metaphor for how serious the sin may be, but as long as you repent, there will be a way out. From Zhu Xi of the Song Dynasty
Volume 59 of "Zhu Xi Yu Lei".
