Ramana Maharshi Foundation UK: What bhāvana should one hold during self investigation?

In a Zoom meeting with the Ramana Maharshi Foundation UK on 9th December 2023, Michael answers various questions about Bhagavan’s teachings. The first question Michael answered was: I have a question about the attitude (bhavana) one should hold when conducting self-investigation. There are 2 different ideas I can read in Bhagwan's teachings: The first being Investigating the Self as I or Who am I or What am I or I am I. The second is God is I or Bhagwan is shining as I or I am Brahman They both lead to attention on the self, but the feeling is subtly different. The first one is more analytical, and driven by a curiosity. The second one devotional, and is driven by a longing to be one with Bhagwan. I understand that these ultimately the same path, but to me these carry subtly different perfumes. Can you comment in this, please?
