Nitya, or Eternity, refers to the concept of timelessness and the infinite nature of existence. In various philosophical and spiritual traditions, it signifies a state beyond the limitations of time, where past, present, and future coexist. This idea is often explored in Hinduism, where Nitya represents the eternal aspect of the soul, contrasting with the transient nature of the physical world. In Indian philosophy, Nitya is associated with the ultimate reality, often linked to the divine or the Brahman. It emphasizes the permanence of certain truths and principles, suggesting that while the material world is ever-changing, the essence of existence remains constant and unchanging.
