The count of Bina, which reaches 67 in 5772, the end of the eight kings of the left, is associated to the count of Din, which reaches 507 in 5786.
Likewise, the count of Chochma, which reaches 67 in 5777, the end of the eight kings of the right, is associated to the count of Chesed, which reaches 507 in 5776.
The count of the years of exile reaches 507 in 5783. It also has an associated count, a greatly hidden count, associated to Arich Anpin, which reaches 67 in 5768, the end of the eight kings of the center. Similar to the exile count, the associated hidden count occurs every 10 years, so that it reaches 68 right before 68 of Bina, and 69 right before 69 of Chochma.
The wise will understand that 56, 59, 60, 66 and 66.5 of the hidden count must be associated to seminal redemptive events. The same is true for 1, which occurred in 5108.
