“When a Jew wears a four-cornered garment, he has a mitzvah, a commandment, to attach four threads to each of its corners. These threads are called tzitzit. One of these threads is the color of tekhelet… which is a reflection of the blue of the sea, and the blue of the sea is a reflection of the blue of the sky, and the blue of the sky is a reflection of a mystical concept called the Kisei HaKavod, a throne on which, so to speak, Hashem sits.

…

[In this week’s Parasha, Korach thought that] if one thread of tekhelet can exempt a four-cornered garment of any other color, surely a garment that is totally tekhelet should be able to exempt itself! What were they saying? The worldview of Korach is: we have the technology within ourselves; we are already living in the blue heavens.

Korach was not the first nor the last to make the utopian mistake of thinking that all that is needed to perfect the world is within this world. Perfection, however, can only come from G-d. Only He… can bring peace to… all mankind.”
