Answer: A Kabbalist’s thoughts influence the worlds to the extent he can rise above his animalistic state and act independently. What does independently mean? To the degree that he can, through his thoughts, overtake the Creator in His plans, he acts independently.
If I, while studying the wisdom of Kabbalah, understand the thought of creation and everything that happens to me, then I can move half a step ahead of the Creator, like a child who drags an adult by the hand. The fact is, that in this case a person rises to a different level. All Kabbalistic books speak only about this.
It turns out that with my desires, I cause actions of the Creator. As it is written, “The righteous decides and the Creator performs.”
