Nityasundara is a Sanskrit compound formed from nitya (eternal, everlasting) and sundara (beautiful). Together, it means "eternally beautiful" or "one whose beauty is timeless." The word appears in the tradition of Sanskrit poetry, philosophy, and devotional literature, where beauty is understood not merely as physical charm but as an enduring expression of truth, virtue, and divinity. It often symbolizes beauty that transcends time and remains unchanged through the ages.
