The statement suggests that the very mechanism of your thought, your mental processes, is the origin of all your pain and distress. It implies that external circumstances are neutral, and it is your internal interpretation and reaction that imbues them with negative qualities.

From a non-dual perspective, particularly as articulated by Krishnamurti, this goes beyond simple psychological conditioning. The 'mind' here refers not just to the intellect, but to the entire structure of the ego – the accumulated memories, beliefs, identifications, and the sense of a separate self. This egoic structure, constantly seeking security and validation, projects its own fears and desires onto reality, creating a distorted perception. Suffering, in this view, is the inevitable consequence of this fundamental misidentification with the 'thinker' rather than the 'thought'. The constant churn of analysis, judgment, and comparison by the ego creates the illusion of a separate self that is constantly threatened, leading to anxiety, sorrow, and conflict. Krishnamurti's emphasis is on direct observation of this process, without the intervention of the 'thinker', to see the mind's conditioning for what it is.

In your life: Notice when you feel discomfort or pain, and observe if it is the situation itself, or your mind's story about the situation, that is causing the distress.
