Ayyavazhi and Hinduism are two belief systems in India. Though Ayyavazhi continues to officially exist within Hinduism and is considered by some observers to be a Hindu sect, members of the religion claim that it is independent. The most notable distinction from Hindu are the Ayyavazhi religion's concepts of good, evil and dharma.
Hindus view Vedas, Gita, and other texts from the Shastra as canonical scriptures, instead of the Akilam. The Ayyavazhi believe that the Hindu scriptures were once canonical, but now have lost their Substance because of the advent of Akilam. Kaliyan bought the Vedas as a Boon and so all the previous religious books including Agamas and Puranas lost their Substances, leaving Akilattirattu Ammanai as the only book of perfection. Several dubious claims state that the present day Vedas are not accepted by Ayyavazhi as books of Perfection, because there is a quote in Akilam about Venneesan "Avan pilathaal vedamondruntakki" (He created a Veda of his own intention). All previous religious texts have lost their Substance in the vision of Ayyavazhi at the very moment Kaliyan came to the world.
Though Ayyavazhi has many differences from popular Hinduism, it has many beliefs and practices in common. As Hinduism is really a tree of many branches, Ayyavazhi is closest to Smartism and its Advaita beliefs in thought.
