Q: It is said that the higher the Sefira, the greater its desires and screen were before the breaking, and the lower its sparks fell at the loss of the screen. Why?
A: A higher Sefira means a greater desire and thus a stronger screen to match it. Of course, if the screen is lost, a greater desire remains bare. What’s left is a greater desire for the self than in the lower Sefira, whose screen and desire are smaller.
Hence the rule: he who is spiritually greater has greater desire. And if he falls, his fall is deeper, and he becomes worse. It is the same way in this world, but in the spiritual world the distances (differences in attributes) between ascent and descent are enormous.
If you really put your mind to it, you can go through all the passages and advance without paying attention to your moods and your inner mental state.
