Answer: You can discover who you were, but not if you are a beginner studying the wisdom of Kabbalah. Only if you attain your soul will you know all its previous lives, all the states, the levels it has been through, and the connections it had with other souls. You attain its place in the general system, in the general soul that contains everyone, that is called Malchut of Infinity. But you can reach all that only if you work and attain it.
Question: Will I be able to discover who I was in my previous lives?
Answer: Yes, if you need it for your current work. After all, the moment you penetrate the upper world, bestowal and love of others, you have no questions about yourself and about your previous lives anymore, only if you need it in order to advance and reach even greater bestowal.
