Sha'ar Ma'amrei RaZaL, Hagigah, Secret of the Four who Ascended into the Pardes, Lesson 1. Why did these four do what they did? Were they acting with special coordination? What possessed them to endanger themselves as they did? This class reviews how we need to properly understand the Kabbalah of the Ari'zal as a psychological system (Ba'al Shem Tov). This set of lessons explains more about the blemish in the collective human consciousness, referred to in the Bible as Adam's sin. We explain what this means, and how the four Sages, armed with this knowledge sought to penetrate into the source of collective human consciousness to help influence a rectification of how collective humanity perceives the world. We refer to, and fully explain, what it means for Zeir Anpin to raise his Keter (crown), prior to its receiving the brains of Abba (hokhma/wisdom), thus, causing Zeir's Da'at (knowledge) to descend between his metaphorical shoulders, into the realm of the upper portion of his Tiferet (heart). Once we understand the full nature of the problem (in all its psychological practicalities), only then can we proceed to understand what the four Sages were actually trying to do.
