Some more from the beginning:
Nevertheless, though multitudes of phenomena repeatedly arise, rousing and popping about, (such activity) has never yet moved the Mind’s Origin. Still and quiet, empty yet formed it does not stand in opposition to karmic results. So, utilizing an unchanging nature it nevertheless dependently arises so that the pure and the impure are constantly differentiated. Yet, in not abandoning conditions as Thusness, the sage and the common man become one.
It is just like waves which because they are not different than the water’s movement, are just the water differentiated into waves. Furthermore, because the water itself is not different than the stream of flowing waves, it is just the waves manifest on the water. Because of this, movement and quiescence interpenetrate, the ultimate and the conventional interfuse, and samsara and nirvana uniformly pervade one another.
Only consider helping others and forget yourself. Master Hsuan Hua
