Lankavatara Sutra, Chapter 2, Sections V- VI

The whole sutra's at this link. A helpful note explains that the "seven kinds of self-nature" mentioned aren't really explained in the text. It is perhaps that these seven kinds of self-nature are myriad ways of providing a taxonomy or map of existence if you can imagine drawing such a thing, but it (or the concept of it) would not be outside of existence then, would it?

Holders of misguided views "do not recognise an objective world to be of Mind itself which is erroneously discriminated; and, not understanding the nature of the Vijnanas which are also no more than manifestations of Mind, like simple-minded ones that they are, they cherish the dualism of being and non-being where there is but [one] self-nature and [one] first principle."

Again, Mahamati, my teaching consists in the cessation of sufferings arising from the discrimination of the triple world; in the cessation of ignorance, desire, deed, and causality; and in the recognition that an objective world, like a vision, is the manifestation of Mind itself.

Seeing things as they are, and not locked into any one way of seeing, is a manifestation of Mind itself.

Buddhists are sometimes accused by critics as not having any objective view, but the reality is that Buddhism admits the existence of an objective world as a project of Mind itself, one that shows evidence of Mind itself, one that reveals Mind itself.

Now for all you Dogen folks out there, that's why he says to study the self is to forget the self, and be enlightened by the myriad things.

But, according to the Lankavatara's text, so is a vision.

And that's why the Identity of the Relative and the Absolute describes the co-existence and interdependence of the subjective and objective.

Hope that's not too philosophically wonky for my 40 or so readers a day, but if you ever wanted to know where Buddhist writers get their stuff...
