Paulo Coelho. Brida (№ 136153)

All human life on earth boils down to finding Another part of yourself. So, whatever he said - even if he insists that he is looking for wisdom, power, or money. Whatever he achieved, everything will be incomplete and imperfect if they fail to find their Other Part.
(All human life on Earth is to look for the Second Half. No matter whether it makes that goes after knowledge, money or power. Any goal that he achieves will be incomplete if he was not able to find your other Half.)
