Annadanam is a practice of donating food to people, especially to those who are in need or visiting temples. In the context of temples, Annadanam refers to the act of offering free meals to devotees who come to the temple. This practice is considered highly auspicious in Hinduism and is believed to bring great blessings to the donors. Annadanam is often organized by individuals, families, or organizations, who plan to prepare and serve food to the devotees. The food offered in Annadanam is usually simple vegetarian fare and is served to everyone without discrimination based on their caste, creed, or social status. The practice of Annadanam has a long tradition in Hinduism and is considered one of the highest forms of charity. It is believed that by offering food to others, one can attain spiritual merit and good karma, which in turn can lead to prosperity and happiness in life.

Nerul Sri Ayyappa Seva Samiti provides regular Annadanam on every 1st Saturday of Malayalam month and on various auspicious festival days.
