Question: Can a scrooge reach bestowal?
Answer: There is no person who wouldn’t be able to change, provided he is mentally sound. We are all “sinners” and “transgressors.” This is why we turn to the wisdom of Kabbalah: We want the Light to correct us so that we will merit it, will become similar to it.
Nothing in a person can become an insurmountable obstacle. Everybody has an opportunity to correct himself if he avoids quibbling with and scorning spiritual work.
