A heart-warming feature of this temple is that, every month, tirumanjanam (a special festival offering veneration and worship to satisfy the lord) is performed for the deities. In this festival both the Azhvars and Acharyas participate with much diligence and devotion. On Svati Nakshatram, worship is offered to Lord Nrisimha, Sri Garuda, Svami Nammazhvar, Sri Periyazhvar and Sri Ramanuja; on the occasion of Punarvasu celebration is dedicated to Lord Rama, Sri Anjaneya and Sri Kulasekhara Azhvar; during the occasion of Rohini worship is offered Lord Krishna, Sri Andal, Sri Tondaradippodi Azhvar; on Sravana Lord Srinivasa, the Mudal Azhvars (Sri Poygai Azhvar, Sri Bhudattazhvar and Sri Peyazhvar) and Sri Vedanta Desika are worshipped and a grand celebration is held ; in the occasion of Chittirai a grand festival id held to worship Lord Sri Chakrattazhvar, Sri Tirumazhisai Azhvar and Sri Madhurakavi Azvar.
The festival of Ashtabandhana Mahasamprokshana of the Lakshminrisimha temple was first performed on 14th December, 1975. The present temple-complex, with its numerous sub-shrines, is a landmark in Nanganallur in the present day. One crore archanas for Lord Lakshminrisimha were completed in 1978 and special tirumanjanam conducted for the Lord and His Consort. Since then, this temple has been achieving significant popularity. Subsequently, the shrines for Lord Navaneeta Krishna, Lord Kodandarama, Lord Srinivasa, Sri Andal, Sri Chakrattazhvar, the Azhvars and Acharyas were constructed. The Rajagopuram, an awe-inspiring structure is constructed in order to welcome devotees into the temple premises. This Rajagopuram is fifty-five feet high and thirty feet wide, with five tiers and seven kalasas at its top.
Though situated in a bustling suburb and enclosed in on all sides by high-rise buildings, the Lord Lakshminrisimha-Navaneeta Krishna temple is really a refuge of peace, piety and serenity. The sacrosanct is blessed by the visits of His Holinesses Srimad Azhagiyasingar, Srimad Andavan Svami and the Jiyar of Sri Parakala Math. Presently this antique temple is a major draw for many visitors to the city. With socially useful projects like feeding the poor, giving financial assistance to the physically-challenged and maintaining a cowshed, besides arranging for classes in the Vedas and Divyaprabandha, the temple at the same time serves the social as well as spiritual needs of the community.
