Bhagavad Gita, Chapter 14, Verse 2

They who having devoted themselves to this knowledge, have attained to My Being, are neither born at the time of creation, nor are they troubled at the time of dissolution.

A real, specific outcome is promised here upfront, before the actual teaching about the guṇas even begins.

Krishna names the destination first, freedom from repeated birth and dissolution, so Arjun knows exactly why this knowledge matters. Real motivation is built in before the details follow.
