Here's the link to the circuit:

From the simulation, when the 22k resistors are removed the LEDs stop blinking because the current flowing only around capacitor. When either the other resistors are removed or all resistors are removed, the components on the circuit burn out.
What is the function of resistors in this flip-flop circuit?
Thanks for your help.
