Remember the emphasis on the heart. the mind lives in doubt and the heart lives in trust. When you trust, suddenly you become centered.
While the pressures of life are inevitable, if at the end of the day you are unable to completely let go of the day and return to a calm, centered inner state, you are overstressed.
The whole world is a cyclone. But once you have found the center, the cyclone disappears. This nothingness is the ultimate peak of consciousness.
Jesus clearly said that you can do all that he did if you can believe, if you can center yourself in the creative flow, as he was always centered.
We all have within us a centered place of wisdom, harmony, and balance.
