Richard Van Le is a New York City photographer, with impressive images from Vietnam, Thailand and Indonesia.
His website has a handful of galleries, and his images of the Balians (Balinese rural healers) managed to capture the mystical elements of these healers' profession. I documented Balians during my stay in Bali, and I recognize some of them in his gallery. However, it is his work on the Cao Dai in Vietnam which I recommend on TTP.
Cao Dai was established in the Southern regions of Vietnam in the early 1920's as an attempt to create a perfect synthesis of world religions. It is a combination of Christianity, Buddhism, Islam, Confucianism, Hinduism, Geniism, and Taoism.
