In this thread I asked about active and passive suffering.
But I'm not quite sure what I mean.
It may help to know what suchenss is? I know it translates to "as it is"... so is that impermanence? Or something more subtle ?
Suchness means there is no construing. Kalaka Sutta may be useful to know the meaning of "such": http://www.accesstoinsight.org/tipitaka/an/an04/an04.024.than.html
What does Suchness mean when we say "as it is"?
It comes from the fact that whatever we see, is due to the eye perceiving an object and the mind creating an image of the object. If the eye is defective, say colour blind, then the appearance of the object in the mind is different from that for a normal eye.
Even though if we have normal eyes, the object we see is still created by the mind. So what difference is it from what we sometimes see in dreams?
We can only perceived that which is created by the mind and not really know the essence of the objects out there in the world - "as it is" or suchness is the name given to these objects which are inexpressible. Images, sounds, texture, scents and tastes are all we know through the mind.
Moreover dogs perceive the world differently from us so do other beings.
That's my understanding from the Theravada tradition.
A tentative answer from thinking about what I have read:
Suchness is the experience of being burnt, or seeing the colour red.
Myriad phenomena are the qualitative aspects of those experiences - what it is like.
And only qualia are experienced, just as there is no qualia without an experience of them.
