Bhagavad Gita, Chapter 9, Verse 15

Others, too, sacrificing by the Yajna of knowledge, worship Me the All-Formed, as one, as distinct, as manifold.

Several real, different paths are named here, not just one single approved route.

Krishna acknowledges more than one genuine way people actually reach toward the same reality, through knowledge, through practice, through worship of what's visible. Real diversity in approach is treated as real, not dismissed.
