Jupiter represents the journey we take to find the truth of our own existence. He pushes us further and higher. He wants the highest truth and he will not be satisfied until it is unearthed and accepted.
Jupiter rules the sign of Sagittarius and is the ancient ruler of the sign of All That Is, Pisces.
He brings us benefits in the form of gifts and blessings. People with a nice Jupiter placement or transit, have gifts coming at them from all directions. If you're looking to win a lottery, check out how he is aspecting your natal Jupiter at the time of purchase.
