24.177

第二解住雪山，謂雪山中處三有處，一者、狩及獵人并所到處，二者、但猿猴能到非獵人所及處，三者、兩俱不到處。第一處所，喻內典生他。第二處所，喻有學三果。第三處，喻無學地。言又諸愚夫，要觀餘境至不得解脫者，凡夫離欲欣上厭下，追求上境出於下境，乃至仍於非想境界不得解脫。

The second [gate] explains dwelling on the snow mountain: it says that within the snow mountain there are three places: first, the place where beasts and hunters both reach; second, the place where only apes and monkeys can reach and hunters cannot reach; third, the place where neither can reach. The first place is a metaphor for internal texts generating other [rebirths?]. The second place is a metaphor for the three fruits of those in training. The third place is a metaphor for the stage of those beyond training. Regarding 'Furthermore, all foolish ordinary beings must observe other objects up to not attaining liberation': when ordinary beings detach from desires, delighting in the higher and disliking the lower, seeking higher objects to escape lower objects, up to the object of neither perception nor non-perception, they still do not attain liberation.
