I don't see the point in asking what's the meaning of life. The question itself is meaningless. Really, what possible satisfactory answer could there be? "We're training to go to heaven", "We're reincarnating over and over again to attain nirvana", the question of meaning could be applied to these answers themselves. Like enquiring about the origin of things, it comes back to an endless loop.

We ascribe meaning ourselves to the things around us; It's paradoxical to think there's an universal law of meaning to our lives.

And that's where most "spiritual" beliefs fail in my opinion. It's commonly held by them that a meaning or purpose is strictly required in life to have any sense of fulfilment or enjoyment. Yet that's not true; Right now I'm listening a piano track I enjoy very much, I have no idea what it is about or what "meaning" it has, and that doesn't make it any less beautiful.

I find it ironic that the very persons who look down onto science and point out the subjectivity of conscious experience will be the ones who try to apply a bunch of objective rules and dualisms to it.
