One interesting set of parallels:suttametta wrote:The "pith instructions" of Vajrayana and Dzogchen are very good at what they do. I've been looking into the suttas to find how Buddha might have said those same or similar things so I can refer to those instead of the pith instructions.
Dilgo Khyentse's pith instructions (on Dzogchen Meditation)
Thai Forest tradition teacher Ajaan Dune AtuloDilgo Khyentse wrote: While mind is watching mind
Though there is nothing to see, it is vividly clear;
Uncontrived, free, and at ease in that state,
Rest naturally, simply undistracted.

The result of the mind sent outside is suffering.
The mind seeing the mind is the path.
The result of the mind seeing the mind is the cessation of suffering.
The suttas are voluminous and contain instructions at many different levels, from the mundane to the "pith". Not everyone needs instruction in the mundane, and not everyone can understand instruction directly regarding the pith. Part of the Buddha's genius was the ability to teach people at various levels according to their capabilities and inclinations in a way that could help them discover and establish their practice upon the path. Simply giving everyone mundane instruction is not always helpful, and simply giving everyone instruction regarding the pith can lead to deep misunderstandings and misapprehension of the practice. It is a challenge for any teacher to understand their audience and provide teachings of the appropriate format at the appropriate time.DN 22: Maha-satipatthana Sutta wrote: And how does a monk remain focused on the mind in & of itself? There is the case where a monk, when the mind has passion, discerns that the mind has passion. When the mind is without passion, he discerns that the mind is without passion. When the mind has aversion, he discerns that the mind has aversion. When the mind is without aversion, he discerns that the mind is without aversion. When the mind has delusion, he discerns that the mind has delusion. When the mind is without delusion, he discerns that the mind is without delusion.
When the mind is restricted, he discerns that the mind is restricted. When the mind is scattered, he discerns that the mind is scattered. When the mind is enlarged, he discerns that the mind is enlarged. When the mind is not enlarged, he discerns that the mind is not enlarged. When the mind is surpassed, he discerns that the mind is surpassed. When the mind is unsurpassed, he discerns that the mind is unsurpassed. When the mind is concentrated, he discerns that the mind is concentrated. When the mind is not concentrated, he discerns that the mind is not concentrated. When the mind is released, he discerns that the mind is released. When the mind is not released, he discerns that the mind is not released.
