From Dave Lowry's "Sword and Brush"
Too early in the morning? Get up and train. Cold and wet outside? Go train. Tired? Weary of the whole journey and longing just for a moment to stop and rest? Train. Continue on in the spirit of perseverance-this is the advice for the bugeisha who reaches an obstacle in the Way, as surely he will. It is advice that will be lost on the novice. The beginner's enthusiasm is such that he cannot imagine what blocks could lie ahead to halt his progress. If some decisive challenge to his continuing on does appear at this early stage, he will likely abandon his practice altogether. The art has not yet penetrated into his daily life. It can be quit without damage to the psyche. It is the more advanced bugeisha who must face dilemmas and potential obstructions that can have serious emotional and psychological consequences. It is shugyo to which he must turn at these times if he expects to overcome and persevere."
