Before thought becomes an object which relates to a separate subject, thought is intimate and impersonal. Thought is cosmic, like the weather. The personal identification is an add-on that creates the unhappy illusion of a separate subject.
From a conversation with a friend: What is thought? Is it illusion?
Thought is awareness that the mind refers to as thought.
Thought is not illusion, it is awareness.
The illusion is to BELIEVE that thought has an independent reality from awareness.
