Obviously, as the Rebbe never ceased to stress, action – goodness and kindness, is all that matters – however, just like a car is obviously only to get you places, but simultaneously you need to have, both fire – energy, and breaks; so when you move forward, you don’t crash; hence we a. need to be happy, for when we are God-forbid down, we are in parked mode; but simultaneously, if we are just excited, we are liable to crash; so we must hold, as the Zohar teaches, not only happiness, but bitterness; Namely on one hand, life has never been more messianic – never before, have we had more freedom, more wisdom, etc. etc. but simultaneously, we need to feel upset, that Moshiach isn’t revealed, that suffering and confusion prevails!
