Tanya for the 29th-30th of Cheshvan כ''ט-ל' מר חשון
When prayer without proper intent is elevated to the “lower heaven,” its elevation does not bring about that which prayer should effect. For in order for a prayer to have its proper effect, such as the fulfillment of its requests, there must be drawn down into this world a degree of Divine influence that transcends the world, thereby healing the sick, or providing the year’s blessings, and so on. When, however, a prayer is repelled to malchut of Asiyah, i.e., to that level from which all worldly things derive their life-force, then this level obviously cannot provide for whatever the world is lacking. However, when a properly motivated prayer reaches up to za of Asiyah, from there, an efflux can be drawn down into the world to provide whatever the world lacks, thereby fulfilling the individual’s petitions.
