Answer: This is “help against you.” There are two forces leading a person toward the goal. One acts in the direction of unity and the other against. By being between them, a person has freedom of will to choose the right environment and with its help (influence) to choose the path toward the goal instead of the opposite path.
Accordingly, both forces help him from both sides. One force pushes him into the group while the other pushes him out of the group (the environment) so that he is always at the equilibrium between these two forces.
He thinks that he is being pushed away from unity, but that’s not so. He receives the force to overcome exactly proportionate to the opportunity to be strengthened in his environment that he received prior.
A person is never driven to failure from Above, as it is written, “One is only elevated in acquiring the quality of bestowal, and never stopped.” Even if there is an obstacle placed before a person now, prior to that it is ensured that a person will be able to overcome it with his free choice.
It’s the same as how we raise children. We consciously and deliberately give them exercises that are more difficult so they will become smarter and stronger.
