This document provides an overview of secularism in India. It begins by defining secularism as a system that rejects religion in politics and aims to accommodate all religious beliefs. The introduction notes there is no fixed definition and secularism is understood differently in India's diverse political structure. The document then examines how secularism relates to India's constitution, noting that while not explicitly defined, the 42nd amendment added it to the preamble in 1975. It aims to secure justice, equality, and liberty for citizens while ensuring religious harmony and national unity. In conclusion, the document states that India's idea of secularism must be evaluated in its historical context and practices, with allegiance given to constitutional provisions over any abstract definitions.
