The founder of the method for attaining the Upper World was Abraham, a resident of ancient Babylon. He formed a group of like-minded individuals in which he began to implement the idea of equivalence of form with the Creator. Abraham’s group attained a high spiritual level, known as the First Temple. A “Temple” signifies a united Kli, a connection between souls that are in complete attainment of the Creator. The rapid growth of egoism and the descent from the spiritual degree to the level of corporeal pleasures is called the descent into Egypt. The Exodus from Egypt represents the spiritual birth of a person. Our time is the era of humanity’s exodus from Egyptian slavery, through the method of attaining the quality of bestowal, love, and unity. The holiday of Pesach symbolizes the transition from egoism to altruism. There is a clear boundary between corporeal and spiritual actions. Nothing corporeal possesses holiness. Holiness is the quality of bestowal, acquired under the influence of the Upper Light. Initially, Abraham’s group, which was in spiritual attainment, perceived the Upper World and this world as one whole. Thought and action comprised a single system in which spiritual and physical actions were fully aligned. However, after the fall from the level of the First and Second Temples, the followers of Abraham completely lost the feeling of spirituality. What remained were memories of physical actions, which became the basis for religious customs and rituals devoid of spiritual content. Kabbalists, unlike religious individuals, invest spiritual intentions into the performance of such rituals, intentions that correspond to their spiritual roots, even though there is no direct connection between the physical action and its spiritual counterpart. Just as a child playing with a toy truck dreams of a real vehicle, so too do we, performing these earthly customs, yearn for and strive to attain their spiritual roots.
