The part that makes us angry is that we are almost abused.  We have been set in motion to suffer - and it is soooo frustrating to us, it makes us feel hurt, betrayed and abused.

We could not do anything but suffer.  But, we are supported to minimise the negative response to the suffering and to minimise the continuance of the suffering.  Basically we are having our spirits broken, so that we may know our true nature, our truth.  Once at this point, the truth is so absurd and ridiculous that one could not help but have a bemused smile.  If we were to know the truth as most of us are now, then we would be disgusted because with where our thinking is at, for some reason we would feel so ripped off, appalled, and furious.  And this in itself, is kind of titillating, but not in a nasty way.  Behind the buddha smile, is super self control, his mind is expansive and he has insight into the true nature of all things. Initially, he would have experienced hilarity, then he would have experienced compassion for all in existence save himself, and then he would have experienced a feeling that is sortt of like when some one thinks 'how in the world is that going to happen/get done'.

The main reason there is so much suffering in the world, is because we have nothing, and we want something and we don't know what it is or whether its going to be worth it - we are confused, blind, and vulnerable, but we don't know that we are, and we spend a lot of time trying to look like we know what we are doing, know what we want - but for the most part we are distressed, and we need to step back, take some time out, take the pressure off ourselves. 

Quote: "Isn't it that mental illness is the most of the world's suffering?
And it is a fact that this is due to always thinking.

The cause of all suffering is the thinking mind.

In Zen it is said, pain is inevitable,

but suffering is optional.

I was always aghast to see monks set themselves on fire for some noble cause.

Hard to imagine a worse way to die.  But actually, once the nerve endings are burned off, the rest would be fairly painless, though quite fatal.

Then the hard part is to imagine what cause would be so noble as to sacrifice your life?

I believe they were grandstanding.  There is no such issue.  These are they who have learned the discipline of the temple, to set aside concerns of their own physical well being, or consciousness of discomfort, through practice, but instead of reaching inward are still stuck with an outward focus.  Put the two together, and poooof, up in smoke.

Could the 'struggle to survive' that all things go through, from the time of its creation until the time of its death be called, 'suffering'?

Is suffering then no-thing more than the nature of impermanence?

Is reality itself not permanent because it stands alone without contrast?

Is reality itself then not the permanent impermanant?

Is reality itself then not a contradiction?

Is the nature of 'reality the permanent', not then 'impermanence'?

Is not then the nature of reality 'struggle' ?

Is not then the nature of realty 'suffering'?

I prefer to know the nature of reality as a constant endeavour to cultivate.

It makes me feel good, and worthwhile.
