Lord Ayyappa is the main deity in the centuries-old temple complex of Melpaazhur Mana. The idol of Lord Ayyappa is svayambhu (born on its own out of the earth).
Legend has it that one day, a woman went to the thick forest backyard of the Mana to collect grass and spotted an unusual stone. When she used the stone to sharpen her sickle, she saw the stone bleeding. Frightened, she screamed, ran to the Mana and reported the incident. The elders of the Mana rushed to the scene and verified her account.
The story goes that a 'tampuraatti' (elderly Nambütiri lady) who was an ardent devotee of the Lord used to walk two kilometres to the Ayyappankudam temple at Vadayaaparambu every day to worship the Lord. When she became old and was unable to walk to the temple, she became inconsolable. She could not bear this separation from the Lord. Astrological readings revealed that the same Lord manifested as svayambhu in the Mana's backyard in answer to the tampuraatti's prayers. That svayambhu stone thus became the idol of Lord Ayyappa around which a temple was later built. Today, it is known as the Ayyappan-kudam temple of Melpaazhur—the old temple at Vadayaaparambu no longer exists.
