Sampoorna Narayaneeyam Parayanam is a devotional practice in Hinduism that involves the recitation of the entire Narayaneeyam, which is a collection of 1036 verses that describe the glory of Lord Vishnu. The Narayaneeyam is a condensed version of the Bhagavata Purana, one of the most important Hindu scriptures.

The practice of Sampoorna Narayaneeyam Parayanam involves reciting all 1036 verses of the Narayaneeyam in a single sitting, which can take several hours. This practice is believed to be highly auspicious and is often performed by devotees seeking the blessings of Lord Vishnu for good health, wealth, and spiritual well-being.

Sampoorna Narayaneeyam Parayanam is commonly performed in temples and homes by groups of devotees and is often accompanied by the chanting of mantras and the offering of prayers and other religious offerings.

Nerul Sri Ayyappa Seva Samiti conducts Sampoorna Narayaneeyam Parayanam on every 2nd Saturday of Malayalam month.
