Navagraha Shanti Puja is a sacred Hindu ritual performed to appease the nine planetary deities (Navagrahas)—Surya, Chandra, Mangal, Budh, Guru, Shukra, Shani, Rahu, and Ketu. It is conducted to reduce the malefic effects of planetary positions and to invite peace, prosperity, and harmony into life. The puja involves chanting mantras, offering flowers, grains, and specific items associated with each planet, seeking balance and divine blessings.
