Remaining the nature is the best way to eliminate obscurations
The purpose of practicing Dzogpa Chenpo, or Longchen Nyingthik, is also to be able to reach the nature of mind. Therefore, we need to study these teachings, Dzogchen teachings, on how to recognize one’s own nature, how to be able to remain in that nature. And once we are able to remain in that nature, then the remaining in the nature has such [a great] power to eliminate grasping or attachment; and that reduces, eliminates all thoughts and eventually all the emotions into the space of one’s mind. And that is a way to practice Dzogpa Chenpo and that is a way to liberate oneself from samsara, because samsara is basically created by thoughts, by the emotions. So recognizing the nature is the best way to cut off all of these stuffs.
