How best you try,
there is a duality in human nature,
a difference,
one which is instinctive due to biological evolution from lower species fighting through struggle of survival & food chain - this is body constituent of humans.
The other part - capability to question nature of existence, the concious mind.
Is concious part always aware ?
Is instinctive part dominant?
Can a human decide which part should supercede ?
