I looked it up. I couldn't make it through 30 seconds of it. Stay far, far away.

I am familiar with it.

The text is questionable. I think it is just barely philosophically and theologically defensible if one gives it the benefit of every doubt, but there are plenty of opportunities for doubt.

If one is familiar with the Hindu texts on which it is based (I am, to some extent, having studied them in graduate school long long ago), then the questions are redoubled and the defense so much the more complicated and convoluted. Do we really want hymn-texts that require such a defense and explanation?

The music attempts to be chant-like in nature and I think does not utterly fail, but as mentioned above, there are many alternatives that are both better and more clearly theologically sound.

It is not, I suspect, "some other suitable liturgical chant approved by the Conference of Bishops or the Diocesan Bishop". If it is not approved, then it must not be sung at Mass, simple as that. GIRM makes this quite clear (e.g #48, #87)
Using it in church in some non-liturgical circumstance is a quite different question.

Just for the sake of scholarly clarification (not taking issue with the judgment about appropriateness): Kabrir based his poetry on themes and texts from both Hinduism and Islam, but identified with neither.

In modern-day terms he would be called 'spiritual but not religious', as the saying goes.

The 'god' to which his words are offered is non-descript, certainly not Brahma.

(Edit: the word 'Brahma' in his and many hands of the time did not necessarily refer to the Hindu deity. The term may be used as a stand-in for the much older spiritual concept of 'Brahman', which is not a personal deity but a kind of impersonal principle of being. The personal deity, Brahma, is probably a late development, and in general 'not a big deal', in Hinduism proper.)

The sound world it evokes reminds me of Stephen Paulus; I think it's appealing musically. On the other hand, the language of the poem sounds like it's describing Hindu faith, which has a different concept of God from ours. Christians believe that God *created* the material world, and that God is present to the material world, but absolutely distinct from it. The poem seems to present an image in which God and the material world are not that distinct. For this reason, it is not suitable to be performed in Christian worship.

For a similar-sounding piece with a more acceptable text (though I still think it's more suited to a concert than to Mass), look for the "Pilgrim's Hymn" by Paulus: https://www.youtube.com/watch?v=R2q4WlozY2E

Thanks again for your comments. Our music director has decided to put Kabir back on the shelf and use another title. May you all have a blessed Easter.
