華嚴經探玄記 7.19

7.19

In the second [part], on emitting light, emitting from both knees surpasses the toes [of the feet] from before, symbolizing that the practices are gradually superior. Moreover, the knees have the function of bending, extending, and advancing, symbolizing the aspect of dedicating the cause toward the fruit and progressing upwards. Therein are four: 1. the point of emergence, 2. the number of lights, 3. what is illuminated, 4. seeing through conditions. That is, having practiced together at the time of the cause, they are sympathetically united at the time of the fruit; hence they see it.
