הֶבֶל (Hevel), mere breath, all humankind (Psalms 39:12).
“Come and see: When actions prove worthy below, and a person contemplates the service of the Holy King, the act he performs turns into a breath above. And there is no breath without a voice—rising, crowned above, becoming an advocate before the blessed Holy One. Every action in which a person engages that is not in the service of the blessed Holy One turns into breath that goes drifting through the world. And when the person’s soul departs, that breath whirls through the world like a stone in a sling, as is written: The soul of your enemies He will sling from the hollow of a sling (1 Samuel 25:29). Who will sling? That breath conducting it around the world. So, everything done under the sun that is not in the service of the blessed Holy One turns into a breath—but it is breaking of spirit, for it breaks the spirit, rising and falling in the world, as is written: breath and shattering of spirit (Ecclesiastes 1:14)” (Zohar 2:59a).
“A spirit leaving this world who has not grown or spread in this world undergoes rolling and finds no rest, comes revolving into the world like a stone in a sling until it finds a redeemer to redeem it…. The spirit that he left, adhering to that vessel, is not lost—for nothing in the world, be it ever so small, lacks a place in which to be hidden and absorbed; it is never lost” (Zohar 2:99b).
