"In spite of despair staring me in the face on the political horizon, I have never lost my peace. In fact, I have found people who envy my peace. That peace, I tell you, comes from prayer; I am not a man of learning, but I humbly claim to be a man of prayer. I am indifferent as to the form. Every one is a law unto himself in that respect. But there are some well-marked roads, and it is safe to walk along the beaten tracks, trod by the ancient teachers. Well, I have given my personal testimony. Let every one try and find that as a result of daily prayer, he adds some thing new to his life, something which nothing can be compared."
