Bhagavad Gita, Chapter 10, Verse 17

How shall I, O Yogin, meditate ever to know You? In what things, Bhagavân, are You to be thought of by me?

This real question comes from someone already convinced, asking how to actually put that conviction into practice.

Belief alone isn't where Arjun stops, he wants a workable method for meditation, something real to hold in mind. The request itself models what taking a teaching seriously actually looks like.
