I think you might find this fairly recent
interview of Dan on Sacred Sundays interesting as it provides a pretty comprehensive description of what Dan descibes as the 3 Maps of Awakening, Stabilization, and Fruition - Buddhahood.
As mentioned above, Dan, at the suggestion of HHDL, has developed a guided tour of pointing out instructions for western students that has a very high efficacy - practitioners having a significant meditation experience that leads to awaken awareness. His teaching focuses first on developing sufficient concentration to be then guided through the insight practices. His delivery of Pointing Out Instructions is rather exceptional. In the catagorization as described in Dzogchen Ponlop Rinpoche's the article
Pointing Out Ordinary Mind, Dan Brown's instructions are more on the order of Essence Mahamudra. (If you were to attend a Level One Retreat with Dan he might suggest you not read his book in advance as it is very scholarly and detailed and one might develop conceptual attachments that would frustate the guided practice of going beyond ones condition view.) You can find more information about Dan and Pointing Out Instruction at the
Pointing Out Way Meditation Website or
Pointing out the Great Way Foundation where you will also find information regarding very precious advanced Bon Dzogchen Texts including the Kusum Rangshar.
Peter Barth, at the request of Khenchen Thrangu Rinpoche has prepared a Sutra Mahamudra Meditation Manual that one can utilize in gradual practice to develop the awareness of and associated with the ordinary mind. I understand it is a very widely used Meditation Manual that has benefited very many students of Mahamudra. (Ironically, Peter and I were friends 40 years ago working in SF and looking back when he invited me to help build a stupa in the East Bay one weekend, I really wish I had taken him up on that offer-such is life)
In any event, whether introduction throught Sutra,Trantra or Essence Mahamudra Instruction it is very important to develop the understanding of the shifts in awareness and pliancy in moving between the various stages.
"I think that it is of far greater importance than the experience of dramatic instantaneous pointing out that
people be taught mahamudra as a full system of instruction that they can implement on their own gradually
through diligent application using any one of the three texts by the Ninth Gyalwang Karmapa -
An Ocean of the Ultimate Meaning, Eliminating the Darkness of Ignorance, or Pointing Out the Dharmakaya -
or one of the two texts by Dakpo Tashi Namgyal - Moonbeams of Mahamudra or Clarifyng the Natural State."
- Khyabje Khenchen Thrangu Rinpoche
So clearly as discussed by Dzogchen Ponlop Rinpoche - through Sutra Tantra or Essence Mahamudra Pointing Out Instructions can certainly catalyze the introduction to the non-dual awareness of ordinary mind.
Further, the means by which awakened awareness is developed in the Tibetan traditions is generally via the Tantric Union of Bliss and Emptiness, Mahamudra, and/or Dzogchen. Though realized through different means, the resulting awareness is fundamentally the same. (HHDL Dzogchen Heart Essence of Great Perfection p174)
wishing you all well in your practice!!
