"Shiv Mahakal" is a phrase commonly used to refer to Lord Shiva, one of the principal deities in Hinduism. "Shiv" is another name for Lord Shiva, while "Mahakal" can be translated to mean "Great Time" or "Lord of Time." In Hindu mythology, Lord Shiva is often associated with time and is considered the destroyer of the universe, who brings about the end of one cycle of creation to make way for the beginning of a new one. Thus, the term "Shiv Mahakal" is often used to emphasize Lord Shiva's power and timelessness.
