Definition of religion clarifies essential vs non essential practices; constitutional protection limited and subject to regulation. Constitutional protection of religion under Articles 25 and 26 is confined to the essential elements of faith and practice; not every belief, ritual or human activity is protected. Determination of what constitutes essential religious practices is a question of fact requiring contextual, doctrinal and historical evidence. Secular, economic, financial or political activities associated with religion may be regulated by the State and subject to reform in the interest of social welfare.
