If the Creator wishes to bring us to similarity to Him, then how can He arouse in us the feeling of His greatness, the value of the property of bestowal, so that we would want to trade our state of existence for His? He does not have much choice, and we are forced to ascend in small steps while always making attempts to choose a more exalted degree over our present state.
Because of this, the Creator cannot reveal His love to us! In fact, if love were revealed, it would immediately ruin the entire ladder of spiritual degrees and everything that differentiates them.
A child is the head of a family and constantly demands from the parents, assuming they live for him. He is taking advantage of their love. If, however, he is in somebody else’s house, he acts totally differently: He won’t make demands as he would at home; he will be shy and afraid. But at home, he has no shame or fear.
Therefore, if the Creator disclosed His love to us, we, like spoiled children, would never be able to appreciate His greatness and ascend to Him. In this world, we are driven by the natural instinct that pushes us to grow and evolve. But in the spiritual world, this animate instinct doesn’t exist. We have to develop such desire on our own.
Moreover, if the Creator did reveal Himself as a Loving one, we would disregarded Him in everything. Hence, He must hide in order to give us an opportunity to evolve and appreciate His magnificence in the darkness. In the light, we wouldn’t be able to do so.
This is precisely what the impure forces (Klipot) complain about: They would like to discover the Creator before receiving the screen. In such case, we would have no chance to reach bestowal at all.
