The presiding deity of this Kshetra is Lord Shiva as Naganathaswamy. Ketu god is visible as silver serpent with the head of a snake and body of an Asura which is a demon.

Ketu generally does bad things and has a tremendous negative impact on human life. When Ketu is in certain houses or when combined with other Graha gods in specific house locations does also good and can bring excellence in education and prosperity to the family of the person offering the puja.

Parihara homam and pujas at keezhaperumpallam is said to neutralize dhosams related to Ketu with respect to marriage, child birth, sarpa dhosam and other defects carried forward to the devotee from the former birth or previous generations and others.

Which means that the sins done by the previous generations are remembered by Ketu Bhagwan and revenge taken on current generation and this is being averted by this homam.

Consultation with astrology is required to find out how Ketu is going to affect your life, business, education, marriage life, child birth etc..

Ketu can also do good things depending on the house in which he is. The good things are normally connected with improving wisdom and spirituality.

Ketu god behaves in close liaison with Sevvai God especially in relation with health, accident and other health related matters.

Ketu as said can make your life and business upside down unless through astrological studies appropriate prayers or homams are performed.
