Normally we are not awed at scientific facts, even though they are immensely profound. Solar system and the stars, whats their temperature, speed of light etc they are profound as their discovery took immense effort and creativity. They seem obvious because they make sense. Our belief in them is backed by logic.
On the other hand the spiritual principles seems so profound to us. It's most likely because they don't have root in logic, they seem magical.
What's needed is understand the profound logic behind them and hope the spiritual principles became as obvious as scientific facts.
