Baal HaSulam, Introduction to the Book of Zohar, Item 4: To understand these questions and inquiries, the only tactic is to examine the end of the act, that is, the purpose of Creation. For nothing can be understood in the middle of the process, but only at its end.
For now, our questions remain questions. In the beginning of the work we don’t yet understand it and don’t see where it comes from. One must first comprehend creation in its entirety, and most importantly, see the end. That is when we’ll understand the beginning stage.
Indeed, we don’t determine the work; rather, we actualize it and are its consequences. Therefore, we shall know the beginning only from its end.
In contrast to us, the Creator doesn’t need a process that leads from a starting point to an end point. For Him, the beginning of the path, the path itself, and the end comprise an indivisible reality. Whereas we must go through all the stages of our development, and only after we have completed our work will we understand the path we’ve traveled and the purpose behind it.
This is why Baal HaSulam wrote that we must study the entire process to the end. Indeed, while on the path the coveted fruit always seems unripe, spoiled, corrupted, just as with any other thing that has not yet reached its final state.
We will not receive true answers to our questions until we reach the goal, the end of correction. Every question we have is a void, a vessel, into which we must receive fulfillment, which is really the answer. Therefore, questions about the meaning and purpose of our existence become filled with answers only after we have achieved the final goal.
