Tiripurasundari Gayatri Mantra (11 Times)

Tripurasundari vidmahe, kameshvari dhimahi, tanno klinne pracodayat.

This means: Let us contemplate Tripurasundari, let us think of Kameshvari, may that wetness direct.

(If possible recite Lalitha shasranama, Lalitha thirisathi,sri suktham etc.,)
Now you can show Sambrani smoke to all the deities including sri chakara.
After this you can show Ghee Deepam to all deities including sri chakara.
After this we should provide Naivedyam (Prasadam) to god
Whatever food available to you that you can provide in a clean plate
Sprinkle some water on the Naivedyam By telling “ Om bhur bhuvas suvaha”
And recite the following Mantras                                                                                                                      

Om Pranaya Swaha
Om Apanaya Swaha
Om Viayanaya Swaha
Om Udhanaya Swaha
Om Samanaya Swaha
Om Brahmane Swaha

And tell “ Naivedyam Nivedayami”

Pour one spoon of water into the vessel after showing the same to gods.
Now sit calmly and pray to the srichakara goddess Sri Lalitha Thiripura Sundari.
And finally recite the following :

"Avahanam najanami, najanami visarjanam, poojamchaiva najanamani kshamaswa Maheswari. Yatkrutam yatkarishyami tathsarvam twamarpanam, poojam poorna phalam kuru".

Roughly translated it means :

"I am not conversant with the Aavahana, visarjana etc.. pooja rituals and hence forgive me. Whatever I have done and I am doing, I am offering to you. Give me full results"

Take prasadam. And do Namaskaram to Sri chakaram
