All of the faults of samsāra arise from the deluded mind which apprehends a personal self or a self of phenomena. Since this deluded mind also is adventitious like clouds in the sky, from the beginning neither mixing nor polluting the luminous clarity of the primordial basic nature, these faults are individually distinguished from the basic element and are suitable to be removed. Therefore, the essence of the basic element is empty of these faults; it is untainted. Without depending on the polluting delusion, it is luminous and clear by its own nature; self-existing wisdom permeates the thusness of all phenomena. It is not empty of that which it is inseparable from, the basic element of consummate qualities, because in its essence this is the basic nature from which it is inseparable—like the sun and light rays.
