Riddle 4 - What is Being?

Well you ready for the answer to last week's riddle?

First here's last week's riddle:

The root of all sin, it creates not life but death,

Our only solution is to have none,

But even if we declare it, it is still there,

Present in the darkness of our hearts,

Even the purest,

It is our greatest defeat.

Did you get it?
The answer was:

Pride!

Reason? Well I thought of it during the week, while contemplating (peripherally) on a book I had read, it's not the root of all evil, since it's one of the Seven Deadly Sins, and I don't really think it's key, but in the book I read it was kind of what the author was implying, but it is a cause for sin, and I thought, well what is the root of all evil? I thought about how Satan had betrayed God, how he used to be the Morning Star. It was because of his selfishness, that he turned away from being a steward of Humankind, and instead became our greatest threat. So I came to the conclusion that selfishness is the root of all sin, (as is money, such as declared by Jesus) but in all essence, it is because we want what we want, and not what we need that selfishness takes its root. Even if we say we aren't, we are. Just because we give money away, or spend time with the poor, we only spend a limited amount, we don't actually give thought to what we do. So some philosophy there but hey... you never know.

So you ready for this week's one?

Here we go:

We do not exactly know what it is,

We say it is, but not what is thought,

It is different for another when it is true for one,

They are never the same, yet it is one,

It cannot be described, nor shown,

No matter how others try.

It cannot be true, as it can be altered,

It cannot lie, as it tells the truth.

What do you think?

Again answers can be posted as a comment so please...COMMENT!!!! 

That is all!

By the way, this picture has no reference to the answer, I put it up, because it reflects the thought of life, how magnificent and mysterious it is, we don't really think at all, and just take it for granted. AGAIN THE PICTURE IS NOT MINE!!! I just used it for inspiration, click on the picture to see who actually made it.
