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?
