Hmmm. Good thread.
*Life is a big deal. Death is just a transition to another existence so to emerge from death on the other side is a big deal while to depart from this place is not. And all life is a big deal, not just human life. The miracle of life in all its forms.
*Love is a big deal. Not only romantic love but all love.
*Experience and acquired wisdom together is a big deal.
*Peace is a big deal. Not just peace as in the absence of war but true inner peace which signifies that one has come to accept the unfoldment of the ultimate reality.
*Your soul is a big deal. We're all off-shoots of the divine. Seeking and tapping into you soul/high self is a very big deal.
*The divine is a big deal. The divine is the ALL that everything is made of. Call it God, if you will.
I agree with your list of minor things, although of course, there are far more to add.
But one thing I consider minor will really set people off...
*truth. Too many people really believe that there is one truth for which they either spend their whole lives seeking or trying to adhere to when, they will discover at some point along their evolutionary journey, that they create their own truths.
If they honestly examine what they hold to be true, they will find that all of their "beliefs" were lessons taught to them by others.
It took me a long time to let go of other people's truths and to tap into my own soul, my own connection to God, to break free from limiting and misguided ideas. That was a big deal.
