What do I have to do to achieve a high level of spirituality?

Shalom Marcos, Good question! God gave each of us a soul, or a “spark of God”, with the potential to be Godly. By following His directions to be Godly (the mitzvot) found in the Torah, we realize our spiritual potential. For example, He creates, and commands us in the very first mitzvah to create children, as well. He “rests” on Shabbat, and suggests that we do so as well. He constantly gives altruistically (without getting anything in return, for He’s perfect and doesn’t need anything!) and we should be similar “givers” as well. To be as much like God as possible, is obviously the highest level anyone can reach. Gmar Chatima Tova! Rav Ari Shvat
