Performing Lalitha Sahasranama Pooja involves the following steps:

1. Preparation: Cleanse yourself by taking a bath and wear clean, traditional attire. Set up a clean and dedicated space for the pooja, preferably with a picture or idol of Goddess Lalitha.

2. Invocation: Begin by invoking the presence of Goddess Lalitha through a prayer or mantra. Visualize her divine form and invite her to bless the pooja with her divine grace and energy.

3. Recitation of Lalitha Sahasranama: Chant or recite the Lalitha Sahasranama, which consists of 1,000 names of Goddess Lalitha. You can either recite it yourself or play a recorded version. Maintain focus and devotion throughout the recitation.

4. Offerings: Offer flowers, incense, fruits, and other symbolic items to the picture or idol of Goddess Lalitha. These offerings represent your reverence and gratitude towards the goddess.

5. Arati and Prayers: Conclude the pooja by performing arati, waving a lit camphor or ghee lamp in front of the deity, while singing or reciting arati songs or prayers. Express your heartfelt prayers, seeking the blessings of Goddess Lalitha for your well-being, spiritual growth, and the fulfillment of desires.

6. Distribution of Prasad: After the pooja, distribute the blessed prasad, which can be fruits or sweets, to all participants and family members as a token of the goddess's blessings.

It is recommended to study the Lalitha Sahasranama and its meanings beforehand to have a deeper understanding of the divine qualities and aspects of Goddess Lalitha. If possible, you can also consult with a priest or experienced individuals for precise guidance on the procedures and rituals specific to Lalitha Sahasranama Pooja based on your cultural and religious traditions.
