The study of numerology is believed to have its roots in the work of Greek mathematician Pythagorus in the fifth century B.C., and grew to include elements of ancient Babylonian thought, Hebrew Kabbalah, and the occultism of early gnostic Christians.

Today, it's practiced by thousands around the world to predict the future, including author Jesse Kalsi, who calls himself an astro-numerologist.

What's That?

"Astrology is the study of the planets, and numerology is the study of numbers," explains Kalsi.

"So we combine these two to obtain a good flow of energy."

And that flow begins with a person's name, translated into numbers, and date of birth.

"From the date of birth, we derive the basic combination, that is the energy of numbers, and then we tune everything with it."

How Is Aaron Rodgers' Energy Looking?

"His name is very good," claims Kalsi. "His name has a lot of Neptune, and his Saturn energy is excellent."

But as the Packers look ahead to a new era, their quarterback may want to look behind him, as in the number 12 on the back of his jersey.

"His jersey number, 12, is not the best for him," states Kalsi.

"What is helping Aaron is his name. His name is very powerful. He could improve his jersey number. That would definitely bring him more luck."

What Would Be Better?

"It would have to be something like a number 25, or a number 7, which has more Neptune energy, to give him the edge."

That edge, says Kalsi, is the power that flows from jersey numbers that are in sync with players' names and dates of birth so as to to maximize the potential for success.

So for Rodgers and the rest of the Packers, success or failure, playoffs or bust, may be all in the numbers.
