Bhagavad Gita, Chapter 8, Verse 27

No Yogi, O son of Prithâ, is deluded after knowing these paths. Therefore, O Arjuna, be steadfast in Yoga, at all times.

Real, clear understanding of where things actually lead is what keeps someone from getting genuinely lost.

This names a real, practical benefit of everything just explained. Knowing clearly what's actually at stake and where each path leads is described as providing real clarity, not just abstract knowledge.
