Love is the only reality and it is not a mere sentiment. It is the ultimate truth that lies at the heart of creation.

The quotation frames love not as an emotion that comes and goes, but as a metaphysical principle—something closer to a spiritual or ontological ground of being. In this reading, “reality” and “truth” are not primarily empirical facts but the deepest coherence of existence: the force that binds persons to one another and creation to its source. The contrast with “mere sentiment” rejects reducing love to private feeling; instead, love becomes an active, world-making power that discloses meaning. The language strongly resembles Tagore’s recurring themes—divine immanence, unity, and the sacredness of relationship—though this exact wording may be a later paraphrase of those ideas.
