Ramana Maharshi uses words like the heart. He talks about reflection. He uses aham vritti
We imagine we understand what he means by heart. Truth is you either have to ask him for clarification or ask someone at that level
Your own imaginative mind will create a false heart – either something in the chest or an emotional aspect to it.
But that is not the heart
Similarly – the mind or the reflection – is not what we think. The best example of that is given in Rama story with Sugriv
