Therefore, through the occupation of Torah study one can actually draw down the revelation of Hashem’s Infinite Light upon his Divine soul, reuniting it with Hashem’s Oneness as it was in its original source.
In other words, even though we may not be on the level to ascend to the higher spiritual worlds to access the revelation of Hashem’s Infinite Light, but we can access His Light in Torah study. This is because His Light that is hidden in this world is revealed through Torah study, which is Hashem’s Will and Wisdom just as is was in Atzilus.
This is the meaning of “if your heart runs in yearning for Hashem, return to reveal His Oneness in this world,” meaning, that even below, when he is “returning” to this world, he brings down and reveals Hashem’s Oneness through Torah study.
In other words, during prayer a person becomes excited about Hashem’s greatness and awakens a love for Him. Then he realizes that relative to Hashem’s greatness he should feel awe and shame in His presence. But then he realizes that he can connect to Hashem and experience His Light in Torah study after prayer. With this, he brings his yearning for connection to Hashem to fruition.
This is the meaning of “my Husband ‘יִל ָּוֶה-will join’ with me,” meaning that Hashem’s Infinite Light will come down from Above to below and be revealed in me through Torah study.
This is the meaning of the passage Emes Veyatziv (the blessing after Shema):
