Astro-Indian philosophy, or Indian Astronism encompasses a vast array of denominations and derivations, the single largest of which is Prabodhanism, also known as Hindi Indian Millettism, residing within comprehensive form of Saamism, and refers to the presence of Astronism in the Republic of India. This country is under management and philosophical jurisdiction of The Institution of The Philosophy of Millettism for the Republic of India, a national subsidiary for the worldwide Astronist Institution. 

The Institution of the Philosophy of Millettism for the Republic of India oversees the construction and maintenance of observatories and planetariums throughout its jurisdiction. India is split into twenty-nine states and is set to hold two Grand Observatories; the first of which is the capital city of New Delhi and the second in the city of Mumbai. 

This national branch of The Institution of The Philosophy of Millettism manages the official representation and depiction of Astronism throughout this territory, including efforts to protect the identity of the philosophy with the intention of further disseminating it throughout the territory. It is The Institution alone that is granted the status of proprietor to the philosophy in this territory as any other organisations or institutions proclaiming such a role are deemed as unauthorised proprietors and are therefore considered as part of the anti-Institutionist movement. 

History of Astronism in India

Astronism is not currently recognised as a religion in India despite the fact that 454,000 people in India are adherents of Astronism. The situation of religious freedom for Astronists in India has been designated as apathetic in the 2020 Astronist Freedom report by the Astronist Institution.
