I'll tackle them in turn:
1. Inner Peace.
I've heard this vague phrase thrown about quite a bit, but I'm not entirely sure that I understand what is meant by it. (though I
do have a sneaking suspicion that many of those who use the phrase frequently mean completely different things by it).
Since I don't really know what the phrase means, I can't really comment on whether I am looking for it. Maybe I am, maybe I am not.
2. Certain Hope Beyond Death
I don't believe in any life after death. I am not in the slightest bit afraid of death, because I know that when I am dead, I won't be around to experience it! I find it intersting that people constantly justify the "need" for religion, on the basis that without it, the entire population of the world would be living in a constant crippling despair about death - yet if always seems to me, from my own limited personal experiences, that it is usually the religious that are so obsessive about death, and the non-religious who are quite often completely blasé about the whole thing.
3. Everyone is looking to make sense of their troubles, trials, etc.
I guess so.
4. Unconditional Love
It would be nice...although this is more of an ideal to strive towards, rather than something you should expect to realistically achieve. (If you manage to; then good for you!

)
5. The Secret of True Happiness
I think after a few thousands of years of philosophers asking this question, the answer should be clear; there is none.
