Question: The concept of the quantity of yearning and longing can somewhat be understood, but what is the right quality?
Answer: Every person’s quantity and quality are determined subjectively, depending on the root of one’s soul and his mission. Similar to our world, there are all sorts of states we can measure by height and character, by the degree of one’s suffering or joy, the intensity of sensation, and the rate of their influence on a person.
Baal HaSulam gives just three examples for assessing them. Even though we differentiate much more, in the end, they all amount to these three, “in that place, at that time, in that woman” (these concepts are explained in the lesson).
