What is the significance of Chaitra Navratri?

Gurudev Sri Sri - Navratri means the nine nights. In the nine nights you turn inwards. It is a time for meditation, for you turn inwards, and then come out with creativity. That is the significance. Chaitra means the beginning of a New Year. So the New Year beings with nine days of turning inwards, prayer, meditation, and chanting. Recognising the Divinity in the whole creation, and enlivening that aspect.
