Answer: In spirituality there are two opposite qualities that unite together. However, we are unable to grasp this with our earthly mind. That’s because our mind is built so it perceives everything only from the point of view of this world. It works only inside the ego so I understand, feel, and act only with what I receive inside my ego.
For now I cannot work with two forms, two opinions, or two opposite forces. That is why I am always left without any understanding of what is happening. And that’s why we also don’t understand anything in our world.
Even though in our world we exist in one, small ego which desires to fill itself and nothing more; nevertheless, we are governed by upper forces of bestowal. That is why we also don’t understand how this world operates.
Why don’t I know this? It’s because I cannot take into account a different force that operates in the world. This force is concealed from me and its qualities are opposite to me. Yet it nevertheless influences me, evoking reactions in me and making me act in response to it.
I do not detect and am unaware of this second half of our reality, which is operated by the upper force, the force of bestowal. I do not understand it and cannot take it into consideration. That is why I always lack understanding, knowledge, and awareness. And that is why we do not understand the actions of the upper one upon the lower one and the reactions of the lower one to the upper one. What upper one, what lower one? Everything is concealed. And that’s the problem.
Thus, if we are talking about the upper system, it contains the force of the receiver and the force of the Bestower connected together, complementing each other and working together in one net, in one unity, in order to receive for the sake of bestowal. They depend on each other and need one another.
However, in our world we exist in just one force, which is egoistic. Even if we talk about the second force, it still does not connect with the force of reception and they cannot work together. Bestowal is opposite, and that is the entire problem of our world.
