Lankavatara Sutra, Chapter 2, Section XV

I'm still using Suzuki's translation...

There are various Buddhas (themselves a bit of an ad hoc construction) which are concerned with the fact that cause and condition bind everything arise from habit-energy which is accumulated by not recognizing an external world as of Mind itself, and so appealing to the relative over the absolute or vice versa is one-sided (or even the construction itself - the idea of it - is one sided).

And this has moral implications, including but not limited to your relation to your self and your relations with others, and how you perceive and act in all of that.
