For me optimism is two lovers walking into the sunset arm in arm. Or maybe into the sunrise - whatever appeals to you.
There are thousands of ragas, and they are all connected with different times of the day, like sunrise or night or sunset. It is all based on 72 of what we call 'mela' or scales. And we have principally nine moods, ranging from peacefulness to praying, or the feeling of emptiness you get by sitting by the ocean.
Get outside. Watch the sunrise. Watch the sunset. How does that make you feel? Does it make you feel big or tiny? Because there's something good about feeling both.
I like that time is marked by each sunrise and sunset whether or not you actually see it.
I wouldn't be surprised if tomorrow was the Final Dawn, the last sunrise before the Earth and Sun are reshaped into computing elements.
