In this week's Torah portion, Jacob goes forth from Beersheva. He lies down with his head on the stones of a particular place, and he dreams of a ladder planted in earth with its head in the heavens and angels flowing up and down.
(When he wakes, he says "God was in this place, and I -- I did not know!" That's one of my favorite verses of Torah. I love that sense of wonder.)
The Degel Machaneh Efraim -- grandson of the Baal Shem Tov -- teaches that this is a passage about expansive mind and contracted consciousness. The angels moving up and down the ladder are a representation of the natural ebb and flow of our lives as we move from big mind to small mind, from a God's-eye view of the world to a limited human view and back again.
The thing is, our ascent and our descent are inevitably interconnected. Ascent leads to descent which leads to ascent again. When a tzaddik, a righteous person, falls from a high level (perhaps through losing sight of the big picture and getting mired in "small mind"), the experience of having-fallen gives rise to yearning which pulls him back up. Our low places spur us to climb.
I love this teaching about gadlut (expansive consciousness) and katnut (contracted consciousness) -- that they are interrelated; that falling is precisely the first step in rising again. And I love the idea that it's our distance from God, or our distance from expansive consciousness, which makes us yearn to erase that distance and be our best selves once again.
