According to Osho, there is not a grain of truth in the claim that devotion is duality and knowledge non-duality. Both bhakti and jnana culminate in the same non-dual realization; they differ in flavor. Jnana is austere, logical clarity; bhakti is overflowing, love-drenched immediacy. Devotees may speak in dualistic language, but their realization is unitary, beyond words.
Both paths reach the same One: knowledge is clear and dry; devotion is juicy and loving—but neither is truly two.
