Answer: By exercising your free will you can change your destiny any way you want, turn it in any direction, a full 360 degrees. But you can only do it if you know for sure where you need to influence your fate, meaning which tiny hole you need to use to affect all the worlds, all the way to the World of Infinity. You have an opportunity to do this, but it is very narrow.
It is specifically this opportunity that we need to clarify. And after we clarify it, we discover that we want to act specifically in this direction.
There is an entire world around me, which connects with another, perfect world through a thin straw. I am at the bottom with my properties and strengths, my freedom of will is in the straw, and the perfect world is above.
Please go ahead, enter the perfect world! You only need to find the tiny opening, the point of your freedom, among all the directions toward which your desire throws you. And once you discover the opening, how can you concentrate all your strengths into one action in order to go through it into the Upper World?
This is what the entire wisdom of Kabbalah is about! Instead of scattering your forces in all directions where you lack the freedom of will and where everything is predetermined, you find this path of your free choice, gather your strength, and then you reach the spiritual world.
Then you understand that fulfilling the condition of the mutual guarantee, love for the created beings, is exactly the same as meeting the condition of advancement into the Upper World. This is because mutual guarantee is another definition of the same formula that directs you to the exit out of this world, into the passage, and birth in the Upper World.
Naturally, we change our destiny this way. After all, you acquire the free point that Archimedes spoke about when he said: “Give me a place to stand on, and I will move the Earth.”
