以賽亞書 40:6 卡巴拉：Baal HaSulam's Introduction to Zohar

And that which is said in Tikunae Zohar (Tikun 30): Arise for the sake of the Holy Presence, for you have an empty heart that does not understand how to acquire Her, although She is in your midst. This is the deeper meaning of what is written (Isaiah 40:6) “A voice says, call!” The voice, that is in the heart of every Jew, calls out for everyone to pray for the elevation of the Holy Presence, [the Holy Presence] that manifests itself through the unification of all Jewish souls.

(Bringing proof from Job 5:1 “Now call/cry out” that [the word] "call" is synonymous with prayer). However, the Holy Presence says “What shall I call?" Meaning, I do not have the strength to rise from the ground, for “all flesh is grass”, they are all compared to animals that eat grass. Meaning, that they perform the Mitzvot without thought, similar to [the thoughtless actions of] an animal. “And all their kindness is like the blossom of the field” (that is cut off and dries). For all their kindness, they do for themselves, meaning, their intent in performing Mitzvot is only to benefit themselves and not for their Creator.
