Siva (or Shiva) is one of the principal deities in Hinduism, known as the "Destroyer" within the Holy Trinity, or Trimurti, which also includes Brahma the Creator and Vishnu the Preserver. He represents transformation and regeneration, embodying both asceticism and sensuality. Often depicted with a third eye and a crescent moon, Shiva is associated with meditation, yoga, and the arts. His followers, known as Shaivites, worship him through various rituals and festivals, celebrating his role in the cycle of creation, preservation, and destruction.
