We've recently entered the month of Tammuz (June 13-July 12), which is followed by the month of Av (July 13-August 10).
Historically, these months contain a lot of tragedy and difficulties.
This is due to the mazal, the astrological influence, of these months.
If you find it harder to work on certain character traits or you find certain flaws getting the best of you, the mazal (Crab/Cancer and Lion/Leo) is the reason.
You also may notice other people acting "off." The mazal is why.
When we know that others are struggling against unseen forces, it helps us to give them the benefit of the doubt and judge them more favorably.
It helps us to judge ourselves more favorably too.
The good thing about the struggle against the mazal of Tammuz and Av is that it gets us into shape for Elul (August 11-September 9), whose mazal is so much more conducive for love and bonding with Hashem, and teshuvah, which in turns prepares us for Rosh Hashanah and Yom Kippur.
It's all about flexing that teshuvah muscle.
