Dzogchen

From wikipedia under the heading Dzogchen subheading "Esoteric Transmission" here is the following quote:

The Dzogchen teachings are the highest of the nine yana, (Tibetan theg pa, vehicle) of the Nyingma (Wylie: rnying ma) school of Tibetan Buddhism and the Tibetan Bön (Wylie: bon) tradition. Many lamas, particularly of the Nyingma and Kagyu schools, regard them as the most profound teachings altogether.^[9]
The instructions that point to the Dzogchen state are sometimes described as a set of "inner" or "heart" (Wylie: snying thig) teachings. Tibetan Buddhist ascetics consider that the state pointed to by these teachings is very difficult to describe, and can only be discovered through the esoteric transmission and pointing-out instruction by an authentic Vajra Master.^[10]
Although Dzogchen cannot be separated by the Buddhist or Bön tradition, very often teachers emphasize the non religious character of Dzogchen. However, the Buddhist or Bön traditional framework is never negated. Namkhai Norbu Rinpoche says that, as our primordial nature, Dzogchen has existed since the beginning of time and is pointed to by various masters throughout the Universe.

There is an interesting technique of looking for the source of one's thoughts, all the while letting everything else fly by. It is sort of like watching the mind throw up everything good and bad while looking for the source of one's thoughts. This meditation allows one to allow one's mind to clean itself as if the mind is a cup full to overflowing. And if we want to put something new into our minds we have to empty the cup so it can be filled with something new. It is a potential experience of experiencing the mind in a more primal way, in a more primordial way than is ordinarily done in the western world that I grew up in.

In our over stimulated world where every moment has to be filled with media and technology and constantly being busy like an addiction, sometimes it is important to slow down and empty the mind of so much in the end useless trivia and get back down to basics. Life can be complex but sometimes complexity only confuses and misdirects. Often in simplicity and primalcy can one see what is important and ultimately real.

So whether one is looking for God, or ultimate Truth, in a way both things are the same in the end.
