Holy Zohar text. Daily Zohar -133.

Tikkun #10 – continue

The 5 word of Shema Yisrael prayer vibrates like David’s harp with 5 strings that was playing by itself and the tune was elevate with the last word of Shema “אחד”, “One”.

The strings of the Tzizit, the special under garment and the Talit (prayer shawl) are tied in 13 links like the value of אחד and each has 3 wraps to give 39 in total. When the sound of אחד is longer, the person draws more blessings of light and long life.
The 13 links and the 5 knots adds to 18 and the 4 wings of the Tzizit sums it to 72. This is the numerical value of Chessed (loving kindness). Wrapping with the proper knoted prayer shwal, create a channel to the supernal surrounding light.
