Anyone visiting Varanasi must read Geoff Dyer's book "Jeff in Venice, Death in Varanasi." It perfectly captures the spirit of the city.
A beautiful daily ceremony right on the banks of the Ganges River. Brahmin perform several rituals that are mesmerizing with the combination of music, bells, and drums. Hundreds of worshipers came to witness the ceremony, several of whom openly welcomed us to participate. It was probably the most spiritual experience of my life. The following morning we returned to the river and went for a boat ride on the Ganges River in front of most of the major Ghats. The pre-morning trip was so calming in contrast with the excitement of the night before. Seeing people meditate on the Ghat steps along our trip was a reminder on how peaceful this moment was. If you're visiting India - I highly encourage experiencing this for yourself!
