Answer: It must be so! A person is given both the pushing force and the resisting force so that he will discover himself through these two forces.
If a person advances only by the force of nature, it will be the result of the instinctive evolutionary force that has pushed humanity to develop for millions of years. Humanity didn’t develop by itself but was developed by these forces.
When a person wants to develop under the pressure of one external force, and at the same time, there is another external force that is a force of resistance, a person feels as if he is between the hammer and the anvil. This is the point from which a person can develop and discover himself, and grow through these two opposite forces. A person turns into a spiritual creature through the right conflict between the two forces.
The upper force leads a person to clarify things between these two forces in order to form the third force through them, which is called the middle line.
Question: Can we say that there are several spiritual attainments, or is there only one?
It is on top of the conflict between these two forces that we resemble the Creator. There is no other way.
Therefore, all the methods that use different forces, actions, and manipulations simply know nothing about these two major parameters in nature, the force of receiving and the force of bestowal, one versus the other.
