According to Osho, guilt is a programmed reaction from childhood and priestly conditioning that condemned joy. Drop it by seeing the conditioning as false, honoring what naturally brings you joy, and refusing comparisons of higher/lower roles. Recognize you haven't committed 'great crimes'; human acts are small. Let life be guided by celebration - play, create, love - because what brings authentic joy is virtue, not sin.
Guilt is a bad lesson you were taught; drop it by trusting what makes your heart feel light and joyful.
