Here Lord Rama established a shrine to Siva upon Rama’s successful rescue of his wife Sita in Lanka, as recorded in the Ramayana. The central practice here is ritual bathing, a common practice at many pilgrimage destinations—Haridwar and Varanasi, for example. This doesn’t mean bathing with soap, but immersing oneself fully clothed in a river or lake as a blessing. Ritual bathing is found in Buddhism, Judaism, Christianity, Islam and other religions.
The huge Rameswaram temple near the southern tip of India is a prime pilgrimage destination for Hindus of all sects.
