Aintiram (Tamil: ஐந்திறம்) is a Tamil text on architectural philosophy, grammar and cosmology attributed to the legendary Mayan.
In Tamil nationalist mysticism, Aintiram is believed to have been written during the First Sangam period. A text of 50,000 verses called Pranava Veda by Mayan is believed to be an addendum or commentary on the 892 verses of the Aintiram.
The content and application of the Aintiram is taught at The American University of Mayonic Science and Technology established by V. Ganapati Sthapati.
