The Zohar, Chapter “Bo (Come Unto Pharoah),” Item 57:”And He planted that seed in one righteous, which is Yesod de Zeir Anpin, the garden’s gardener.”
I have to imagine that I have a property within me called “Yesod de Zeir Anpin,” also known as the “righteous man.” This is where my seed is, a point from which I will eventually grow.
“And He planted that seed in one righteous, which is Yesod de Zeir Anpin, the garden’s gardener. And the seed in the garden, which is Malchut, is the concealment and hiding of that light. This means that the concealment is not absence, but on the contrary, it is a seed of blessing, that the concealment itself will become light once more, like a plant that buds from the seed.”
Baal HaSulam mentions this example in his article “Freedom of Will.” We need to “implant” ourselves into a Kabbalistic group like a seed is sewed into the earth in such a way that we “reject” (diminish) ourselves before the group. If we do that we become a seed that decomposes, “rots” in the ground in order to let the tree grow.
