Bhagavad Gita, Chapter 8, Verse 26

Truly are these bright and dark paths of the world considered eternal: one leads to non-return; by the other, one returns.

These two real paths are described as constants, always available, not just historical options.

This closes out the description by naming both paths as ongoing, present realities, not distant possibilities. The real choice between them is framed as something genuinely relevant now, not just a piece of ancient cosmology.
