Answer: These goes together very well. “We will do and we will hear” is a pure scientific approach which exists in true science. This is because science constantly reveals phenomena that were previously concealed from us. We had no factual knowledge nor connection to them. All we had was our desire to reveal, develop our perception and abilities, in order to grasp new, additional phenomena, test them on us, on our own flesh, on our senses, and register them. Relying on this data, we gathered a more robust image of reality where we exist.
The same approach operates in Kabbalah. It is a science just like a regular science as it is our aspiration to reveal a new reality. There is no difference.
However, in the regular natural sciences of this world, we are not required to change our senses. We only need to expand them. The research instrument already exists: It is our desire to receive pleasure. We simply must expand it through different microscopes, telescopes, and other tools that raise our sensitivity toward previously concealed phenomena.
The entirety of reality divides into two halves: reception and bestowal. In order to check, examine, and study the reality that is based on bestowal instead of reception, we primarily need to arm ourselves with the corresponding instruments of perception (Kelim, vessels).
It is no longer enough to simply expand our senses. We need to build new organs based on bestowal from scratch. This is called birth in the spiritual world.
In the spiritual world, a different nature where we study the force of bestowal, our ability to test, examine, and register data depends on the expansion and development of our senses. It happens the same way as with our egoistic organs of perception when we build different auxiliary tools.
This is how a higher science called Kabbalah appears. It is referred to as “higher” because it works with the force of bestowal in nature, while the sciences of our world examine the egoistic force of reception.
However, in the end, we discover that there is only one source for both the force of reception and that of bestowal. This is because this division only exists in relation to us; we divide reality this way. However, in truth, they both come from one source: the upper force.
