As any reader of the first books of the Bible cannot help but observe, the Children of Israel were an ungrateful lot:
God had delivered them from bondage in Egypt, had divided the Red Sea for them to pass through, had given them manna to eat, and more.
But, nevertheless, they complained and acted ungraciously at the least provocation.
The explanation is that a proper understanding of what is happening to one requires distance, a proper perspective, and adequate tools.
When a person is too strongly loved and too quickly rescued from a predicament, it may be difficult to respond suitably.
One may need a thousand years or more in order to begin to grasp the wonder of one's deliverance.
In any situation of a miraculous nature, the participants may be hard put to realize what is happening to them, and the response will often come only much later.
Altogether, the capacity to grasp any aspect of Divinity is quite limited, and the explanation adapted to the human understanding of a certain generation may sound absurd to another generation.
Therefore, it is only an act of humility to refrain from being too critical of the expressions used by the teachers of the past, who after all, were only endeavoring to impress their audiences with the greatness of God by using figures of speech, images, and symbols appropriate to their time.
What is important is that there always was an attempt to bring the Divine into the range of the people's grasp, even to the simplest of men.
The mere fact of saying that there are numberless "mansions" containing numberless worlds and that each world is infinitely greater than our own is not enough to do more than freeze us intellectually, thereby canceling the importance of our existence.
