Theertham There are sixty-four Tīrthas (holy water bodies) in and around the island of Rameshwaram. According to Skānda Purāṇa, twenty-four of them are important. Bathing in these Tīrthas is a major aspect of the pilgrimage to Rameshwaram and is considered equivalent to penance. Twenty-two of the Tīrthas are within the Rāmanāthasvāmī Temple.
