Shelach 5775

The posuk (15:39) tells us that by looking at the tzitzis we will be reminded of all the mitzvos. How so? What about the tzitzis will remind us? Rashi explains that the numerical value of the word "tzitzis" is 600. It consists of 8 strings and 5 knots. That adds up to 613, the total amount of mitzvos. The Ramban says our reminder comes from the techeiles string. The root of the word "techeiles" is "tachlis," meaning "purpose." The blue string reminds us of our purpose in life, to bring G-dliness into the world through the mitzvos.
