9:51 on the Clock

The number 51 isn't in your numerology chart, but the number 9 is. Your life path number is 9. Although I did no numerology calculations to back this up, I'm thinking the 51 is a connection with your mother.

Your life path number 9, the month for September, by itself probably wasn't enough vibrational attraction or subconscious connection with your mother's birth date to direct your conscious attention to that particular time.

When you started dating the person you mentioned, there was additional attraction, probably enough to make the connection with your mother click into place. Like yours, his life path number is 9. Further, 9 is also his personality number.

Three major positions with the number 9, one in your chart and two in his, the connection to the month of September, is likely to have been enough to remind you of your mother at the time you first saw 9:51 two months or so ago.

Recognizing your mother's birth date in 9:51 may have caused a wondering if it meant something. If yes, the mystery set up at that point is likely why you keep seeing the time.

The mind doesn't like mysteries. It has a compulsion to solve them. While attempting to get it solved, it tries to direct your conscious attention to the subject of the mystery whenever it's available in your environment.
