Secularism refers to the separation of religion from the state. A secular state can't promote any one religion as state religion

Anusha Bathla 6 years, 4 months ago

Secularism means the separation if the power of state from the power of religion That is the government cannot interfere in religious matters and the majority religious group cannot have access to the financial resources and state power

0Thank You

Yogita Ingle 6 years, 4 months ago

Secularism in India means equal treatment of all religions by the state.
With the 42nd Amendment of the Constitution of India enacted in 1976, the Preamble to the Constitution asserted that India is a secular nation. However, neither India's constitution nor its laws define the relationship between religion and state. The laws implicitly require the state and its institutions to recognize and accept all religions, enforce parliamentary laws instead of religious laws, and respect pluralism. India does not have an official state religion. In matters of law in modern India, however, the applicable code of law is unequal, and India's personal laws - on matters such as marriage, divorce, inheritance, alimony - varies with an individual's religion. Muslim Indians have Sharia-based Muslim Personal Law, while Hindus, Christians, Sikhs Muslim Indians live under common law. The attempt to respect unequal, religious law has created a number of issues in India such as acceptability of child marriage, polygamy, unequal inheritance rights, extrajudicial unilateral divorce rights favorable to some males, and conflicting interpretations of religious books.
