Our spiritual journey is deeply reflected by the evolution of the voice and by the ways in which we communicate with others. Our fears, softness, sharp edges, peacefulness, and joy are carried to others by our tone, words or lack of words. As people become more whole and in tune with themselves, they usually speak with greater simplicity, resonating from both heart and head.
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.
