It is impossible to invent something that doesn’t exist in nature. Perhaps there is no analogue in the material we build it from or on the same level, but it must exist. We take all the examples and the analogies from what already exists in nature; we cannot invent anything that is totally new.

It is fundamentally impossible. There is only one new point in all of creation—something from nothing (Yesh Mi Ayin). Everything else, except this “initial act of creation” (Genesis Maase) is a consequence of the meeting of the vessel and the properties of the Light in different connections. So we can take an example only from the existing attributes and create parallel forms.

Everything that we build in our world, which means in our egoistic feelings, is called “this world,” and there are examples for that in nature. If we want to continue our development by studying nature’s wisdom, we have to develop a new perception that is focused on bestowal. Then we can also fulfill the examples of in order to bestow by ourselves.

We cannot receive examples of the upper attributes from this material world, and so all the scientific progress ends on the border between our world and the upper worlds. Even before science has exhausted itself, our material desire to receive reaches a dead end and comes to an end. Our development ends at a certain point since we cannot find new examples we want to implement in this world.

Most importantly, we have lost the desire to look for them in order to invent new things and thus advance on the material level. We are in a point of transition, on the verge of the revelation of new spiritual desires.
