Why is fasting done during Navratri?

Fasting during Navratri has both spiritual and scientific significance. Spiritually, it symbolizes self-control, discipline, and devotion to Goddess Durga. Devotees believe that by fasting, they purify their mind and body, making them more receptive to divine energy. Scientifically, Navratri usually falls during seasonal changes (autumn and spring), and light, sattvic food helps detoxify the body and boost immunity. Common fasting foods include fruits, milk, buckwheat (kuttu), and sabudana.
