From this primary Buddhist perspective (approached differently in the Zen path, but the same understanding is being pointed to), all form at every level is dependent on an unborn mind-like awareness matrix (of formless nature) from which every duality, physical or mental, arises. This is the light that enables all phenomena and all experience of phenomena.
To try and seek transcendence is counterproductive, because the transcendence is inherent in everything and every moment right now. To look for it elsewhere is to be distracted and diverted from where it is - here, in whatever is happening of any sort, right now.
One difficulty people find is that this apparently, and does include all the bad as well as the good. But both sides of any polarity that is manifesting before us and within us require first the light of awareness to be in contact with that emergence of mental or physical phenomena, any emergence Buddhism sees as dependent on many other aspects, never self existing of itself, including what we see as "bad" at that moment.
But also this greater awareness, when we are simply open to it, brings all polarities out of a dual view into a non-dual space, of what is referred to as one of bliss and with a certain magic like quality that, somehow, spontaneously effects all in the moment. The vision of this is something that can happen spontaneously within us. It can also lessen and return at other times.
This "bringing together" is equated with compassion and is seen as a quality that arises also spontaneously, "of itself". Other Dzogchen writings include the statement that the "antidote is in the poison". From the light of awareness, which is described also as a mirror reflecting all that appears within it, spontaneously and mysteriously manifests a transcending, wisdom-enabling, transforming compassion.
Not all at once. But each moment of full, relaxed, accepting, open awareness by our selves is enabling this "treasure" in our ourselves and every manifestation. All our decisions and actions in daily life (with this non-interfering openness) will be overtly no different immediately (usually), except they will be somehow over time be more apt, more effective and more fulfilling.
It is thus described as "Perfect" in the sense of being utterly complete, resolving all within its spontaneous ever-ongoing flow from moment to moment, in every now.
You may have wanted something simpler, but I went with the flow. I hope I have not compounded things.
