In this place of tzimtzum in our hearts we can form pure intentions, this is called the wisdom of our hearts. These intentions of our hearts can then draw down divine inspiration, drawing HaShem into our personal place of tzimtzum. Within this hollow of our hearts we can recreate the world anew.
I have to marvel at the revellation here that takes place and almost perfectly mirrors the original top-down creation of the world. This mirrored version is (obviously) bottom-up. Instead of pure undifferentiated Godly light, we start with our passion-filled heart. In this place of utter distance from God, recognized by its defining characteristic, an unquenchable thirst to connect to God, we hollow out a small space. In this space, we pour the highest thing we have to offer, our holy thoughts. Through the pouring of our holy thoughts into this tiny hollow, we draw down God's infinite light, the light that he first cleared away to make a hollow in which to create us.
Through this Torah we can really get a clear glimpse of how the awakening from below, is at once utterly different and startlingly similar to the awakening from above.
Rebbe Nachman says that it is in exactly this way that Tzaddikim can perform miracles and wonders.
For ourselves we can take away from this a new way to open ourselves to prayer.
