At the critical juncture of life, you must not be timid. Life is about passing one level after another, especially the first level, which is extremely difficult and arduous. The first wave of people lacked courage and retreated when they saw the hopeless battle. They never had the hope of seeing the real world again in their lives.
The second wave of people lacked patience. They had a try-it attitude, were brave but not wise, climbed to the edge of the well to take a look, and fell back. They couldn't find the temple door with a pig's head. They simply touched the boundary of this real world and retreated. They couldn't keep up with one step, and couldn't keep up with every step. From then on, they could only imagine their lives.
The third wave of people were brave and wise, fighting to the death and never retreating. After passing the first level, they would immediately pass the second level. They passed seven or eight levels in life, constantly enlightened, and constantly touched the real world.
For them, every step was very good. They endured the difficulties and obstacles of all levels and enjoyed all the real beauty of this world.
