It may be expressed through prayer, ritual, meditation, music and art, among other things. It may focus on specific supernatural, metaphysical, and moral claims about reality (the cosmos, and human nature) which may yield a set of religious laws, ethics, and a particular lifestyle. Religion also encompasses ancestral or cultural traditions, writings, history, and mythology, as well as personal faith and religious experience.

The term ‘religion’ refers to both the personal practices related to communal faith and to group rituals and communication stemming from shared conviction. ‘Religion’ is sometimes used interchangeably with ‘faith’ or ‘belief system’, but it is more socially defined than personal convictions, and it entails specific behaviours, respectively. The development of religion has taken many forms in various cultures. It considers psychological and social roots, along with origins and historical development.

In the frame of western religious thought, religions present a common quality, the ‘hallmark of patriarchal religious thought’: the division of the world in two comprehensive domains, one sacred, and the other profane. Religion is often described as a communal system for the coherence of belief focusing on a system of thought, unseen being, person, or object, that is considered to be supernatural, sacred, divine, or of the highest truth. Moral codes, practices, values, institutions, tradition, rituals, and scriptures are often traditionally associated with the core belief, and these may have some overlap with concepts in secular philosophy. Religion is also often described as a "way of life" or a life stance.

From the above it is clear that every religion is based on dogmas, superstitions and rituals. Hence, there is no point in changing one's religion. One religion is as good or as bad as the other religion. Supposing a Hindu becomes a Muslim, and then in that case he would stop worshiping the various idols but instead of that start worshiping Kaaba where also an uncut stone is placed. So, from one set of rituals, he would go to observe another set of rituals. Therefore, for national harmony and also for avoiding communal riots etc., there should be a clear anti-conversion law which would make it binding on a person born in a religion to retain that religion so that a Hindu (which term includes Sikhs, Jains and Buddhists, according to the Constitution) would not be able to convert to Islam or Christianity or any other religion.

Similarly, a Muslim would have to remain a Muslim and a Christian would have to remain a Christian. This is as on the date of passing the anti-Conversion law. However, a man of every religious thought or let us say religion for simplicity's stake would have an option to become agnostic or atheist in which case he would not remain a Muslim, a Christian or a Sikh, etc., the religions which believe in God but he would still be able to remain a Hindu, Jain or Buddhist because these religions allows one to be agnostic or atheist. I would urge the Government of India to bring out such a law immediately.
