瑜伽論記 4.59

4.59

In the third and fourth dhyānas, since receiving what is attained is itself the elimination of coarseness and weight, there is no other distinct essence; possessing two capabilities, they delight the faculties and abandon coarseness and weight. Although there are other dharmas within the dhyānas, because these are superior and of great benefit to those cultivating absorption, they are specifically established as factors. However, the extensive analysis of the meaning of these dhyāna factors will be explained further in fascicle sixty-three.
