The Constitution of India does not explicitly state that India is a secular state. However, the Preamble to the Constitution and several of its provisions show that the founders of our Constitution were committed to making India a secular state. The Preamble to the Constitution states that India is a sovereign, socialist, secular, democratic republic. The word secular was added to the Preamble by the 42nd Amendment in 1976. Before that, the Preamble only referred to India as a sovereign, socialist, democratic republic. The inclusion of the word secular in the Preamble reflects the commitment of the makers of our Constitution to creating an India where all religions would be treated equally. 

One of the most important principles of the Constitution is that it guarantees equality of all citizens regardless of their religion, caste, creed or gender. This principle is enshrined in several articles of the Constitution. 

For instance, Article 14 guarantees equality before the law and Article 15 prohibits discrimination on the grounds of religion, race, caste, sex or place of birth. Article 16 guarantees equality of opportunity in public employment. 

Article 25 guarantees freedom of conscience and free profession, practice and propagation of religion. These articles make it clear that the makers of our Constitution were committed to creating a secular state where all citizens would be treated equally. The Constitution also provides for certain special rights and protections for religious minorities. 

For instance, Article 30 guarantees the right of minorities to establish and administer educational institutions of their choice. Article 29 guarantees the right of any section of the citizens to conserve their culture, language or script. These provisions show that the Constitution makers were committed to creating a secular state where all religious communities would be treated with equality and respect.

They believed that India is a land of many religions and that all should be treated equally. 

The Constitution guarantees equality of all citizens regardless of their religion. 

It also provides for freedom of religion, which means that everyone has the right to practice their own religion.

The makers of our Constitution were aware of the religious diversity of India and wanted to make sure that all religions were treated equally. They also wanted to create a state where people of all religions could live in harmony. India is a secular state because the makers of our Constitution wanted to protect the rights of all religious groups.
