According to Osho, Narada's and Shandilya's Bhakti Sutras differ not in truth but in tone: each sage sings the same divine reality in his own authentic voice. The Divine is an inexhaustible, flowing current; wise ones draw directly from it, so their expressions vary like unique waves of one ocean. Their distinctions are creative nuances (emphasis, rhythm, flavor), not contradictions.
They point to the same love of God but speak in their own words, like two singers with different voices singing the same song.
