A number of Indians have tried to define secularism as sarva dharma samabhava (equal respect for all religions). I cannot say whether they have been naive or clever in doing so. But the fact remains that secularism cannot admit of such an interpretation. In fact, orthodox Muslims are quite justified in regarding it as irreligious. Moreover, dharma cannot be defined as religion which is a Semitic concept and applies only to Judaism, Christianity and Islam. Hinduism is not a religion in that sense; nor are Jainism and Buddhism, or for that matter, Taoism and Confucianism.

As far as I know, Nehru never defined secularism in its proper European and historical context.

"Many Hindu intellectuals are just not able to comprehend the fact that there is no human aspiration or experience which lies outside the range of Hinduism; it provides for even demon-Gods. In contrast, all religions are in the nature of sects, though they cannot be so defined because of their insistence on their separateness and, indeed, hostility to Hinduism"
"In view of deliberate attempts in recent decades to project Buddhism and Jainism as separate religions, distinct from Hinduism, it would be in order to deal with them in passing. the attempts have clearly been motivated by the design to separate their followers from the parent body called Hinduism just as Sikhs have been to an extent. Though not to the same extent as in the case of Sikhs, the attempts have succeeded in as much as neo-Buddhists and at least some Jains have come to regard themselves as non-Hindus.
In reality, however, Buddhisms and Jainism have been no more than movements within the larger body of Hinduism, not significantly different from Lingayats, Saktas or Bhaktas of more recent times."
"The BJP is not a communal party; it cannot be, for the simple reason that Hindus have never been, and are not, a community in the accepted sense of the term. They represent an ancient civilization not known either to draw a boundary between the faithful and the faithless, the blessed and the damned, or to engage in heresy hunting and its counterpart, persecution of other faiths. Hindus are, in western terms, pagans."
