The Indian state keeps away from religion in certain matters such as the election of government, deployment of officials, etc. for administration. However, it has also given rights to the minorities to set up their own educational institutions and also provides funds to them.
The state also tries to create a reformed society by making laws against the outdated and cruel customs which are against human rights in the religions.
There are certain rules by which a particular religion is exempted from them. For example, the defence personnel in India cannot keep beards but the Sikhs can.
