The energy, which is the womb of the entire creation, which has given birth to all that is,is called Devi, or Divine Mother. Everything in this creation, your body, mind, intellect, ego; the physical and subtle energies, are all the manifestation of the one energy into many different forms. And this one energy is called Devi. That is why Mother Divine is also called Shakti which literally means energy.

If you have to lift your hand, it requires certain energy, certain strength for something to happen. So, this whole universe is governed by Shakti and tapping into this Shakti is what Navratri is all about. And Pooja(worship) and spiritual practices are a means of tapping into this Shakti. So during the nine nights of Navratri, the Devi is worshipped in all Her names and forms.

The divinity is everywhere but it is dormant, and Pooja is the process to awaken it.

As said by Gurudev Sri Sri Ravi Shankar
Founder of The Art of Living

Durga, Lakshmi, Saraswati

During the nine nights and ten days of Navratri, the three forms of the Devi (Durga, Lakshmi, and Saraswati) are invoked.

When we honor the Devi during the nine days of Navratri through chanting of the many names and qualities of the Devi, we enliven those qualities within us, and they manifest in us according to the need to the hour.
