I understand that

  1. R1 and R2 make a voltage divider.
  2. initially Q1 is not conductive, so is Q2?
  3. initially C1 acts as short circuit, so flashes the light L1 for a moment?

Please correct me if wrong. Can someone breakdown this circuit step by step? Is there an easy analogy to solve such combinational transistor circuits generally?
