" The point of the pilgrimage,” as a Buddhist priest told the traveling author Oliver Statler on his journey around the Japanese island of Shikoku, “is to improve yourself by enduring and overcoming difficulties.” In other words, if the journey you have chosen is indeed a pilgrimage, a soulful journey, it will be rigorous. Ancient wisdom suggests if you aren't trembling as you approach the sacred, it isn't the real thing. The sacred, in its various guises as holy ground, art, or knowledge, evokes emotion and commotion.
