Tikkun 21 – 49
The Cantillation marks are in the aspect of the surfing water of the sea. They express the connection of the supernal light to the Torah, which is the sea, ים. The numerical value is 50 and that is for the 50 gates in the Torah that lead us to Binah.
The Torah mentions the exodus 50 times יציאת מצרים, that literally means going out of the straits of the sea מצר ים.
Each time the Torah mention this term we should meditate to pass through another gate to break limitation and ascend to Binah.
