Rabindra is originally from India and teaches classes and performs treatment using Reiki methods. He told Kongo that it takes him about four hours each day to stack the rocks and he disassembles the whole thing every evening. He basically uses the riprap lining the quay at Seaport Village for his raw materials. It should be noted that a host of scientific agencies including the American Cancer Society, Cancer Research UK, and the National Center for Complementary and Alternative Medicine have found that there is no clinical or scientific evidence that Reiki is effective in the treatment of any illness. In any event, despite untold billions of dollars of research, we still lack a cure for cancer.
Kongo has not opinion on Reiki (what do monkeys know anyway) but he enjoys meeting interesting people and Rabindra is certainly one interesting character.
Below is a video of Rabindra stacking rocks.
Travel safe. Have fun.
