Bhagavad Gita: Arjuna inquired? (Attaining the Supreme ,Text 1,2 Chapter 8)

arjuna uvaca

kim tad brahma kim adhyatmam
kim karma purusottama
adhibhutam ca kim proktam
adhidaivam kim ucyate

(Attaining the Supreme, Text 1 Chapter 8)

Arjuna inquired: O my Lord, O Supreme Person, what is Brahman? What is the self? What are fruitive activities? What is this material manifestation? And what are the demigods? Please explain this to me.

arjuna uvaca

adhiyajnah katham ko ' tra
dehe' smin madhusudana
prayana-kale ca katham
jneyo ' si niyatatmabhih

(Attaining the Supreme, Text 2 Chapter 8)

Meaning: Who is the Lord of sacrifice, and how does He live in the body, O Madhusudana? And how can those engaged in devotional service know You at the time of death?
