Left brain is numbers. The senses and what is considered, logical, tangible, scientific reality. 

Right brain is paint splatter, feelings and personal experience. 

Which one should we listen to? Which one is to be followed and respected in this delicate experiment of a dance we call living?

Its 

Logic vs Faith
Chaos vs Grand Design
Silent Death vs Eternal Conscious Life

Are we capable of anything we set our minds to? Could we reach into the void between sky and shine and grab tight where Icarus fell short?

Does a cancer know it is a cancer? Does it feel remorse as leeches through the host, choking the life from its surroundings, do we?

Its the cold clarity of the automatic model, that we are just talking monkeys on a cold rock, spinning through nothing, against the warm delusion of the collective godhead.

Chemical vs Astral
Insanity vs Genius
Don't be ridiculous vs Hallelujah
But if all matter is just particles of light condensed together, humming at a certain frequency, are we not the echoes of singing stars? The walking proof of our ancestors love transcending space and time? Symphonic legacies all wandering alone, but at the same time, harmonizing together, so is existence not a song?

Chaotic grinding gears vs scripted flowing dance
Trophies vs trying
Yin vs yang

Yet we know these opposing forces are not one true, one false, but both equal parts of the same whole.

So its really 

Fear vs Love.

Now Love is conducive to both halves of the brain, left brain now has a safe place to survive and a chance to continue the bloodline, which is is primitively logical, and the right brain and Love have always gotten along fairly well, many a paint was splattered for Love.
So if we are these screaming stardust warriors, are we not nature Itself? And is to love the nature surrounding us, and how it helps us survive, not to love ourselves?
Right brain says be grateful for the moments, left brain says be aware and present in the moments, but I say, with the full fusion of two separate forces now entwined, that if you

 Love every natural flowing moment of experience you are given, and upon Dying the television of conscious thought should simply turn off, then at least you left the channel a better show than when you got here. But should the TV just change channels, then let's check out that other channel.
Or perhaps the TV turning off is a channel in itself? Perhaps its just about perspective, and how you choose to see it all, so why not choose one based in Love?
