Arudra Darshan 2026 is a significant Tamil festival dedicated to Lord Shiva, particularly His Nataraja form, symbolizing the cosmic dance of creation and destruction. Celebrated during Margazhi Masam when Thiruvathirai Nakshatra aligns with Purnima, it is considered auspicious for worship. Devotees seek blessings for prosperity, spiritual growth, and divine grace, viewing it as Lord Shiva's spiritual birthday, distinct from Maha Shivaratri observed elsewhere in India.
