Liberation shall be found through death. Death is the meaning of life and will always be. It's the only logical explanation I can think of, and I've pondered about existential questions since I was a toddler.
Some would arguably say that reproduction is the meaning of life, but I believe humans are different from animals here. Humans have a greater sense of bonding and monogamy, although example of monogamic relations can be found in some bird species.
Death is the end, and after that... We do not know what happens, if anything.
I believe humans will cause their own extintction judging by the state of todays society. Something has gone wrong, humans strive for material wealth as opposed to spiritual health. The indirect striving for happiness through possessions is the curse of man. It has always been and always will be.
I don't believe in big bang though. Magic rain on dead rocks cannot cause life, at least not according to my definition of common sense. Now, I do not intend to offend any "big bangers" here. Its just my opinion on what I regard as a trivial theory.
Some people believe in the astral, that there is a paralell dimension or a spirit world. This theory isn't that inferior to me, as I have had some "not of this earth" experiences through deep meditation. I was able to reach a state where I didn't feel my physical body and achieved a state of serene peace. This lasted a few seconds and was achieved for hours and hours of meditation.
In my current stressed out state, there is no way I can achieve something similar again. Sadly enough...
