Sharad Purnima

Sharad Purnima (also known as Kumara Purnima, Kojagari Purnima, Navanna Purnima, Kojagrat Purnima or Kaumudi Purnima ) is a religious festival celebrated on the full moon day of the Hindu lunar month of Ashvin (September to October), marking the end of the monsoon season. The full moon night is celebrated in different ways in various cultural regions across Indian subcontinent.

On this day, many Hindu divine pairs like Radha Krishna, Shiva Parvati and Lakshmi Narayana are worshipped along with the Chandra, the moon deity, and are offered flowers and kheer (sweet dish made of rice and milk). Deities in temples are usually dressed in white color signifying the brightness of moon. Many people observe full day fasting on this night.

Significance
Sharad Purnima celebrates the night that the rāsalīlā (a circular dance) was performed between Krishna and the gopis (milkmaids) of Braj. To participate in this divine dance, Shiva took the form of Gopīśvara Mahādevā. Vivid descriptions of this night are given in the Brahma Purana, Skanda Purana, Brahma Vaivarta Purana, and the Linga Purana. It is also believed that, on this full moon night, the goddess Lakshmi descends on the earth to watch the actions of human beings.

Kojagari Purnima concerns the observance of the Kojagara Vrata. People perform this vrata under the moonlight after fasting for the day. Lakshmi, the Hindu goddess of wealth, is significantly worshipped on this day as it is believed to be her birthday. Indra, the god of rain, along with his elephant Airavata is also worshipped. This day is celebrated by Hindus differently in various regions of India, Bangladesh and Nepal.

Sharad Purnima holds great significance in the Swaminarayan Sampradaya, particularly within BAPS, as it marks the birth of Gunatitanand Swami, who is ontologically believed to be Aksharbrahman.

Bengal, Assam & Tripura
In Bengal, Tripura and Assam, the night is known as Kojagari Purnima. Kojagari translates to 'one who is awake' in Bengali. It is believed that Goddess Lakshmi visits people's houses on this night, checks whether they are staying awake, and blesses them only if they are awake. In northern and central states of India, such as Uttar Pradesh, Bihar, Jharkhand, Madhya Pradesh and Chhattisgarh, kheer is prepared during the night and kept under the moonlight in an open roofed space overnight. It is believed that on this night, moon rays carry amrita (elixir of immortality), which is collected in the kheer. The kheer is then eaten as a prasad on the next day. Also, goddess Lakshmi is worshipped on this night.

For some Bengali tribes, the day is celebrated a few days before or after the exact day, especially in the Dyao,  Brahmo, and  Cumulang traditions, as per various traditions determining which days are auspicious for celebration.

In Maharashtra, it is popularly known as Kojagiri Paurnima. People make masala milk and keep it outside under the moonlight, as moon rays are believed to carry amrita.

In many parts of Gujarat, Garba is performed under the moonlight.

In Mithila region of Bihar, special celebration occurs in the house of newly married groom. Groom's family distribute betel and Makhana gifted from bride family to their relatives & neighbours.

In Odisha, on this day unmarried women fast, with the popular belief of getting their suitable groom (kumara). Unmarried women worship the moon on the occasion of this festival. The puja starts in the early morning when the moon sets with new dress. A kula (a basket made of woven bamboo strips) is filled with rice puffs, sugarcane, betel leaves, betel nuts, cucumbers, coconuts, and seven other fruits such as apples or bananas. In the evening the full moon is worshiped again, and worshippers break their fast by preparing a dish containing the fried paddy and fruits from the kula, along with curd and jaggery and offer it to the moon god before a tulsi plant. After this, maidens play games and sing songs under the light of the full moon.

Nepal
In Nepal, the day is known as Kojagrat Purnima and it concludes the 15–day Dashain festival celebrations. Kojagrat translates to 'one who is awake' in Nepali. Similar to the traditions of eastern India, Nepalese Hindus wake up all night offering reverence to goddess Lakshmi. It is also the last day to receive the Dashain tika from ones relatives.
