A BEGINNING

When we begin questioning about our existence,perhaps the question to begin with is -"Do we exist at all in the first place?"
Our existential crisis, or suffering from not understanding our existence,begins from grasping to the illusion that we exist.
What are we... but a collection of shifting feelings, perceptions, mental formations and consciousnesses...in a body of constantly changing elements?
If there is no real self, who is the questioner?
