There are two kinds of light in this painting.
The one that we insist not to see directly and take it for granted
This is the light that always helps us to see the truth and it's always close to us.
The other that we are trying to reach as far away may be it.
This is the light that blinds with its shine, dazzles, alter.
And like James Thurber said:
“There are two kinds of light - the glow that illuminates, and the glare that obscures.”
