Q: Is it good to share what I feel with others?
A: You must not share your relationship with the Creator, or describe how you feel about Him with anyone. But that does not apply to the knowledge you have acquired in the wisdom of Kabbalah.
When you disclose your feelings before an uncorrected person (not the knowledge, which can be conveyed), you allow, even if against your will, that person’s uncorrected thoughts and aims to penetrate your soul. The other person is not aware of it and wishes you no harm. However, his lack of correction is joined with yours and harms both of you.
