BY 42nd amendment act, 1976 the word "secular" was added in the preamble. But do you really think that our country is secular.
General conception of the word secular: A secular state is a concept of secularism, whereby a state or country 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 or equivalent, although the absence of a state religion does not guarantee that a state is secular.
The sole purpose of adding the word secular in the preamble was to attain a egalitarian society where each person is treated equally and gets equal opportunities for developing his skills and earn his livelihood without being affected by social, economic and political conditions.
if this was the object then from where the concept of minorities developed. Each and every person is expected to get equal opportunities then why there is a cry for attaining minority status(in respect of jamia millia islamia recently getting minority status) .
