瑜伽論記 11.34

11.34

Ji says: as for saying 'cultivating the perception of impermanence, the perception of suffering, and the perception of non-self,' these are the three Dharma seals. That it does not mention emptiness is because it is identical to non-self, and thus it is not stated. Furthermore, regarding saying that one cultivates the perception of excellent benefit with respect to nirvāṇa, this refers to recitation, meaning constant recitation. Gāthā is verse, and udāna is a condensed presentation; this says that with respect to nirvāṇa one cultivates the perception of excellent benefit, which is constant recitation.
