Question: When I read Kabbalistic books, I undergo many experiences and sensations. But after reading, everything disappears from my head. What to do with it?
Answer: This is good! While reading, you experience all of this, pass it in your states. Do not worry that they disappear. The main thing is that you have passed through them, that they have worked within you as long as they should have worked.
Do not worry about what you have forgotten, what you read; you should not hold on to anything: not in memory, nor in feelings, nor in your heart, nor in your mind. Do not try to hold on to anything! Let everything flow. The next state will always be higher, better than the previous one. Make room for it!
