1. Preparation: Cleanse yourself by taking a bath and wear clean clothes. Find a quiet and sacred place where you can perform the pooja undisturbed.

2. Pooja Altar: Set up a small altar or a designated area where you will perform the pooja. Place a picture or idol of Goddess Durga on the altar. You can also decorate the altar with flowers, lamps, and other traditional items.

3. Invocation: Begin the pooja by lighting a lamp and invoking Goddess Durga. Chant the Durga Mantra or any other mantra that you resonate with to invoke the presence and blessings of the Goddess.

4. Chandi Saptashati Recitation: Start reciting the 700 verses of the Chandi Saptashati. You can divide the recitation into chapters or sections over multiple days or perform it continuously in one sitting. Use a copy of the Chandi Saptashati text or follow along with an audio recording if available.

5. Concentration and Devotion: While reciting the verses, try to maintain a focused and meditative state of mind. Visualize the form of Goddess Durga and immerse yourself in her divine energy and presence. Offer your sincere prayers and intentions to the Goddess.

6. Offerings: Along with the recitation, you can offer flowers, fruits, incense, and other sacred items to the Goddess as a symbol of devotion. It is also customary to perform the "Arati" by circling the lit lamp in front of the deity.

7. Conclusion: Once the recitation is complete, express your gratitude to Goddess Durga for her blessings and guidance. Seek her continued protection and strength in your life.

Please note that the Chandi Saptashati Parayanam pooja may vary in specific rituals and traditions based on regional customs and individual preferences. If you have access to a priest or a knowledgeable person, it is advisable to consult with them for accurate guidance on the pooja procedure.
