For it is written (Shir HaShirim 2:6): “His (Hashem’s) left hand is under my head [and picks it up to connect to Him],” meaning that the aspect of the “left hand that pushes away,” i.e., Gevura-Severity, is what causes “picking up my head.”
Meaning, because Hashem gives us the ability to fear Him, which is from the “left hand,” this enables us pick ourselves up to connect to Him in love.
And (as the above verse continues) “His (Hashem’s) right hand embraces me,” in a manner of “the right hand that draws close,” i.e., Chesed-Kindness, which causes us to become enveloped in His Light, like a hug.
Through attaining the fear of Hashem, we become receptive to experience His Light when we awaken our love for Him in prayer. (This concept is mentioned in Tanya chapter 43, that the more fear of Hashem one has, the more love of Hashem he can experience.)
