Setu, a Sanskrit word, carries multiple meanings depending on its context. In the context of Hindu philosophy, it refers to a bridge, often symbolizing the connection between the material and spiritual worlds. The most famous "Setu" is the Rama Setu or Rama's Bridge, a chain of limestone shoals between Pamban Island, also known as Rameswaram Island, off the southeastern coast of Tamil Nadu, India, and Mannar Island, off the northwestern coast of Sri Lanka. According to Hindu mythology, this bridge was built by Lord Rama's monkey army to rescue his wife, Sita, from the demon king Ravana. In a more contemporary sense, "Setu" can also be a common Indian given name or surname. Additionally, "Setu" is sometimes used in the business and technology world, referring to digital platforms or networks that connect various entities or systems, often emphasizing their role in bridging gaps and enabling seamless communication.
