自下第六明生雜妄，樂令人貪，或成生可畏，先喻、後合。喻中三句：一生雜妄樂喻，「嶮岸」喻於人天之身，臨墮三塗故名為嶮，於彼生中愚闇障心名為「草覆」，於彼生處妄樂牽情名「於岸邊多有甘露」，修因納得名「有食者」，天報延長名「壽千年」，處斯無苦名「永除病」，受之多慶名「安穩樂」；二凡夫貪惑喻，凡求彼樂名為「貪味」，不知彼樂臨墜三塗故言「不知下有深坑」，造善求之名「前欲取」，不覺命盡名為「脚跌」，顛墜三塗名「墮坑死」；三菩薩捨離喻。

From here below, the sixth [section] clarifies that birth is mixed with delusions, and its pleasures cause people to crave, thereby establishing that birth is to be dreaded. First is the simile, and then the application. Within the simile there are three clauses: First is the simile for birth being mixed with delusive pleasures: the 'perilous cliff' illustrates the bodies of humans and gods, which are called 'perilous' because they verge on falling into the three wretched realms. The dark ignorance in that birth that obscures the mind is called being 'covered with grass'. Delusive pleasures tugging at emotions in that place of birth is called 'there is much sweet dew on the edge of the cliff'. Cultivating causes and obtaining them is called 'those who eat'. The retribution of the gods being extended is called 'living for a thousand years'. Being in this state without suffering is called 'permanently eliminating illness'. Receiving this with much rejoicing is called 'tranquil joy'. Second is the simile for ordinary beings' craving and delusion: ordinary people seeking that pleasure is called 'craving the flavor'; not knowing that this pleasure verges on plunging into the three wretched realms is called 'not knowing that below there is a deep pit'; performing good deeds to seek it is called 'stepping forward desiring to take it'; not realizing that life is ending is called 'slipping with one's foot'; and plunging into the three wretched realms is called 'falling into the pit and dying'. Third is the simile for the bodhisattva's abandonment.
