All the suffering and joy we experience depend on conditions.
— Bodhidharma
To enter by reason means to realize the essence through instruction and to believe that all living things share the same true nature, which isn't apparent because it's shrouded by sensation and delusion.
As mortals, we're ruled by conditions, not by ourselves.
Many roads lead to the path, but basically there are only two: reason and practice.
Neither gods nor men can foresee when an evil deed will bear its fruit.
