We are created in the image of God, a presence that transcends understanding. Many unseen factors determine our success. Yet we have free will, and our own choices at every step make us ultimately responsible for what happens in life.
To achieve what we desire in life, it is helpful to follow the precepts of the great religions. But, most of all we need to follow the wise counsel of the heart.
The pure and impure stand and fall by their own deeds. - Buddhism
Calamity and happiness are in all cases our own making - Confucisnism
