We Have Neither Attainment Nor Perception of any Matter
As there is no perception of the Creator whatsoever, is it impossible to attain the essence of any of His creatures, even the tangible objects that we feel with our hands.
Thus, all we know about our friends and relatives in the world of action before us are nothing more than “acquaintance with their actions.” These are prompted and born by the association of their encounter with our senses, which render us complete satisfaction although we have no perception whatsoever of the essence of the subject.
Furthermore, you have no perception or attainment whatsoever even of your own essence. Everything you know about your own essence is nothing more than a series of actions extending from your essence.
– Baal HaSulam, “The Essence of the Wisdom of Kabbalah”
