Diodes in the feedback of Wien Bridge Oscillator

Hello! I was just able to find a working wien bridge circuit, thanks to Multisim....but i have a question, in the circuit below, what exactly is the purpose of the 10k ohm resistor and the two parallel diodes in the figure? will the 10k ohm resistor short out eventually??? I know that it is used to have a gain > 3 at the beginning, then decrease to just 3...also the potentiometer in the figure must be at 40% for oscillation to start....
