Spiritual roots also have an influence on their material branches. Everything is determined by the order of dissemination of the forces of Light, which affect our material, the desire to receive pleasure. There is a special periodicity and causality in the affect of these Lights.
They have a mechanism, which puts into gear and controls everything from the head of the World of Atzilut. From there, from Arich Anpin, Aba ve Ima, YESHSUT, and ZON, which exist in special relationships to each other, we receive changes, which are called: year, month, week, days, minutes, nights, as well as many different more internal states.We are talking about qualities and the combination of qualities, which have a great influence on this world.
If a person wishes to connect himself to the spiritual root and to place himself under a greater influence of the Upper Light, in order to become closer to it, then one must use these periods of a special influence on us from above. If one wishes to ascend spiritually, then during such periods in our world, which are called holidays, he needs to unite with the intentions that pertain to such influences.
In ARI’s book, The Gates of Intentions, he explains how a person should act during such special periods of influence on our world, as Rosh HaShana, Sukkot, Pesach (Passover), Shavuot, and so on. If we are talking about Pesach, then its most significant characteristic is the Light of Hassadim. When a person receives the Light of Hassadim for the first time in his life, he acquires the quality of bestowal and rises above his ego.
Therefore, it pays for us to think more about the Upper Light, which, at this time, has a greater power to raise us above our egoism and to keep us above it, in the quality of bestowal. Subsequently, we will already be able to advance further and to feel the spiritual world with all its details.
Thus we should spend all the days of Pesach thinking about the unification between us and the Upper Light, which raises every one of us above his personal egoism. This needs to be our main intention over the course of the whole holiday.
