When you wrap yourself in your tallis, you should see the techeles.¹⁴. Today, we have lost the tradition as to how to how to manufacture the necessary dye. That is, you should be overwhelmed with awe of G-d.¹⁵43b, in which the blue of the tzitzis is meant to remind one of the ocean, the ocean of the sky, and the sky of the Throne of Glory. Thus, looking at the techeles can engender awe of G-d. Tzava’as HaRivash, p. 3b
