A secular state is a concept of secularism, whereby a state is or purports to be officially neutral in matters of religion, supporting neither religion nor irreligion. A secular state also claims to treat all its citizens equally regardless of religion, and claims to avoid preferential treatment for a citizen from a particular religion/nonreligion over other religions/nonreligion. Secular states do not have a state religion (established religion) or equivalent, although the absence of a state religion does not necessarily mean that a state is fully secular; however, a true secular state should steadfastly maintain national governance without influence from religious factions.
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 religious laws instead of parliamentary laws, and respect pluralism. India does not have an official state religion. The people of India have freedom of religion, and the state treats all individuals as equal citizens regardless of their 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-basedMuslim Personal Law, while Hindus, Christians, Sikhs and other non-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.
