Kabbalah Perspective to Tzitzit with Audio

Daily Zohar - Shelach Day 5 Based on Zohar Bamidbar 175b

"Rabbi Yehuda said: the Holy One blessed be He says [to Israel], 'Whoever wishes to follow Me in awe should follow this heart, and the [watchful] eyes that are over it'. [One of the most important tools in growing in holiness is to guard one’s eyes and not to look beyond one’s immediate presence.] Who are these eyes? It is as in, "The eyes of G-d [Zeir Anpin] are towards the righteous [i.e. malchut]." (Psalms 34:16) However, "you seek not after your own heart and your own eyes." [that see only the physical world and lead you to sin]. What is the reason for this? It is because "[of your eyes] after which you go astray." (Num. 14:39)"
