1. If a person does not wear a garment with four corners then he is not required to wear fringes (tzitzit). However, it is good and proper that a person should be cautious to wear a small tallit every day, in order that he should remember the mitzvot at every moment. Thus, there are five knots in accordance with the five books of the Torah, and there are four corners, so that in every direction he faces he will also remember. It is proper to wear tzitzit on his garments, and at the very least, it is proper that one should wear tzitzit at the time of prayer.
2. It is a Mitzvah to grasp the Tzitzit with your left hand near your heart while reciting Kriat Shema. This is alluded to [in the verse] "And these words shall be...on your heart".
3. It is good to look at your Tzitzit as you are putting them on while you say the blessing.
4. Some have a custom to look at their Tzitzit when they reach the verse "And you shall see them," and to place [their Tzitzit] on their eyes. This is a beautiful custom. Addition: Some have the custom to kiss their Tzitzit when they look at them, and all of this is a way of showing love for the Mitzvah (Beit Yosef).
5. When one looks upon the tzitzit he should look at the two fringes in front of him that have ten knots in total that remind him of his existence, and they also have sixteen strings and ten knots that count as twenty six as in the [letters in the] divine name.
6. Great is the punishment for one who does not fulfill the mitzvah of tzitzit, for regarding such an individual it is said, that "it might take holds by the end of the earth" (Job 38:13), whereas the one who is careful in the mitzvah of tzitzit is meritorious and sees the face of the divine presence.
