I wanted to know the various sources and meanings behind wearing Tzitzit, thanks.

Tzitzit is a Mitzvah from the Torah, like any other Mitzva. It's basic reason is to remind us of Hashems Mitzvot when we see it. It also provides a spiritual sheild from sinning. It's special in being a Mitzva that surrounds the person, like Sukka and Eretz Yisrael, which is a special spiritual level. Rabbi Ro'i Margalit
