In western culture, the number 13 is considered to represent bad luck. The “cursed” number takes its reputation from Norse mythology.
Luck doesn’t really exist except in our minds. If luck was real then life would be a series of random events. I believe there is a Divine Order to our lives that is bigger than anything we can understand.
Embrace everything that happens to you in life, even the bad stuff. When you accept that there is no randomness, only structure, it makes the bad things easier to navigate. A little easier, anyway…
