• I am aware of the world
• I am aware of my body
• I am aware of my thoughts
• I am aware of my emotions

So the entity that the I represents cannot be the any of the above entities that I am aware of

<aside> 🌍 I am the witness of this entire world but I mistakenly think that I am the body - which happens to be the mutable matter of which I am conscious of!

Adhyātma is the technical word for the consciousness principle (a.k.a. SELF) which happens to be MY real nature.
