Indeed [the question about the need for all of us to study Kabbalah vanishes], if we set our hearts to answer but one very famous question… This indignant question is a question that the whole world asks, namely, “What is the meaning of my life?” In other words, these numbered years of our life that cost us so heavily, and the numerous pains and torments that we suffer for them, to complete them to the fullest [in vain!], who is it who enjoys them? Or even more precisely, whom do I delight?
It is indeed true that historians have grown weary contemplating it, and particularly in our generation. No one even wishes to consider it. Yet the question stands as bitterly and as vehemently as ever. Sometimes it meets us uninvited, pecks at our minds and humiliates us to the ground before we find the famous ploy of [forgetting about it and] flowing mindlessly in the currents of life as always.
3) Indeed, it is to resolve this great riddle that the verse writes, “Taste and see that the Lord is good.” [This can be done with the help of the science of Kabbalah as the method of the revelation of the Creator and thereby also resolve the mysteries of our entire life.]
