Nature and grace are viewed as flowing together from God. They are both sacred gifts. The gift of nature ... is the gift of "being"; the gift of grace, on the other hand, is the gift of "well-being." Grace is given to reconnect us to our true nature.
You come to see that suffering is required; and you no more want to avoid it than you want to avoid putting your next foot on the ground when you are walking. In the spiritual path, joy and suffering follow one another like the two feet and you come to a point of not minding which 'foot' is on the ground. You realize on the contrary that it is extremely uncomfortable hopping all the time on the joy foot.
