After my last encounter with the Cao Đài religion, I was really hoping to get to the Cao Đài Holy See in Tay Ninh. I managed that recently. Services are held four times a day, at 6 AM, noon, 6 PM, and midnight. The most attended one is apparently noon, and hordes of tourists (myself included) show up to watch the service. Odd that the service should be open, but over the heads of the worshippers are two galleries running the length of the temple lined with gawkers.
This picture shows the signing of the "Third Alliance Between God and Man." The three people shown are, from left to right, Sun Yat-sen, Victor Hugo, and Nguyen Binh Khiem. Don't ask. Or go see the Wikipedia article linked from the last entry.
