The best time to stir up holy bitterness is when you are anyway sad because of mundane problems. Or, when you are sad for no apparent reason. Grab that moment of sadness and redirect it to become the holy emotion of bitterness. This will alleviate your worldly sadness, and unbelievably enough, transition to into joy! It is not about brushing the issues under the rug and making light of them. It is about continuing to honestly recognizing the dark space of our body and animal soul. But bringing something else into the picture -- that infinite reality that we hold within us: our Divine soul.  Can you sit with that thought? The pity of this most precious soul within a deep and dark exile? This will motivate you to do something about it! And ultimately, as we will explore next class G-d willing, will bring you to great joy.
