Physicists spend a lot of time in a state of confusion. It's an accupational hazard. To excel in physics is to embrace doubt while walking the winding road to clarity. The tantalizing discomfort of perplexity is what inspires othewise ordinary men and women to extraordinary feats of ingenuity and creativity; nothing quite focuses the mind like dissonant details awaiting harmonious resolution. But en route to explanation - during their search for new framewaorks to address outstanding questions - theorists must tread with considered step through the jungle of bewilderment, guided mostly by hunches, inklings, clues, and calculations. But don't lose sight of the fact that nothing comes easily. Nature does not give up her secrets lightly. The Fabric of the Cosmos by Brian Greene
The above quote can easily be applied to the study of Talmud, and the study of the Torah as a whole. Just as in the fundamental particles and principles of the physical world, confusion reigns and clarity comes only after a lifetime of struggling in bewilderment, the same is true when trying to comprehend the fundamental particles of the spiritual world.
And the same is true of life in general as well. Too often we think that things should be clear. Our life's purpose and mission should be clear to us, perhaps we think it is clear to us. We resent at times the need to struggle to properly understand Torah.
But that is how it is meant to be. This is the world of the struggle and bewilderment, not that of clarity.
