Srimad Bhagavata Sapthaha Maha Yajnam is a Hindu religious ceremony or ritual that involves the recitation of the Srimad Bhagavata Purana, one of the major sacred texts in the Vaishnavism tradition.

The word "Sapthaha" means "seven days," and "Maha Yajnam" means "great sacrifice." During this ritual, a group of learned scholars or priests recite the entire Srimad Bhagavata Purana over a period of seven days.

The recitation is usually accompanied by various other religious rituals and ceremonies, including the offering of prayers, devotional songs, and the distribution of prasadam (blessed food) to the attendees.

This ceremony is very auspicious and is believed to bring spiritual and material benefits to the participants. It is often performed by devotees who seek blessings, purification, and spiritual growth.

Nerul Sri Ayyappa Seva Samiti conducts Srimad Bhagavata Sapthaha Mahayagnam every year. Many devotees from various parts of Navi Mumbai and Mumbai attend the Mahayagnam.
