The beliefs and rituals associated with the Mannarasala temple are different from most other temples, and this is one rare temples where the puja pattern is headed by a Brahmin lady. Legends say that when the Muthassan left for the Cellar (More details in History), he had given certain rights and instructions to his mother. He instructed that 'Mother herself must offer me worship. On certain special days men may be given a chance to worship. After Mother's time, the senior-most Brahmin lady in the family will have the status of the Mother. From the time the mother assumes this high position Mother should live as a brahmacharini and observe penance. Those who worship me with devotion will have children, will be cured of diseases, will have long life and health and wealth; the men of the family will have the title of 'Vasukisridevi''. He reminded that the rituals and customs suggested by Parasurama are inviolable.
Valia Amma is the heart and soul of Mannarasala. The resplendent brightness of Valia Amma who has turned into a symbol of Naga deities through fasting and other austerities has not dimmed in the least by now as a result of the performance of rituals and poojas. Pilgrims cannot leave Mannarasala without seeing that fascinating divine glow with their own eyes and feeling contended. The sight of faithful devotees, who come here to seek the blessings of Nagaraja, waiting for long to see the flicker of the eyes of the great mother, so serene and compassionate and filled with blessings, continues even today. That holy lamp sheds brilliant light on the temple and the environment, and endows it with heavenly glory. It has been the presence of and the contact with, the Mother, who has assumed a divine form and reached the heights of spirituality, that has been the sole source of prosperity for the members of the family as for the devotees.
