Answer: It is actually so. Everything that occurs in our world, materializes according to specific direction and influence of the upper world.
But we are not able to trace these influences. We cannot say which root, which force of the upper world, influences our world and what specific effect this force wants to realize. We don’t see the upper world; we don’t understand its program, its influence on us.
From the lower world, the upper world can be attained only if we will gradually come to resemble the nature of the upper world; there is no other way. Until we understand the entire, complex, system of influence on us from above downward and reveal it from below upward, we will not attain anything.
The law of root and branch points to the fact that there is a connection between the upper root and the lower branch: in each atom, in each action, on all levels of inanimate, vegetative, animal, and human matter, in thoughts, in forces—in everything.
But we do not observe this connection and cannot say which root is the cause of which effect in our world or how we can make some kind of changes in the root from the effect in order to improve the end result and its impact on us. This is actually the subject of study for Kabbalists.
The science of Kabbalah studies this interaction and offers practical advice and techniques for how to bring oneself to congruence with the upper root so as to be able to affect it and receive from it a desired response.
