The statement "You mustn't be aware of your thoughts, you must be aware of awareness" emphasizes a deeper level of mindfulness and self-awareness. Here's an explanation:

Awareness of Thoughts: When you are aware of your thoughts, you observe them as they arise and pass. This is a useful practice for mindfulness, as it helps you recognize patterns, reduce reactivity, and gain insights into your mental processes. However, it still involves engagement with the content of your mind.

Awareness of Awareness: This takes mindfulness a step further. Instead of focusing on the thoughts themselves, you shift your focus to the awareness that observes these thoughts. This means recognizing the pure consciousness or the "space" in which thoughts, feelings, and sensations occur. This awareness is always present and unchanging, unlike thoughts, which are fleeting and variable.

By being aware of awareness itself:

1. Detachment from Thoughts: You create a distance from your thoughts, recognizing that they are transient phenomena within your consciousness rather than your true self.
2. Deeper Presence: You experience a deeper level of presence and stillness, as you are not caught up in the content of your mind but are resting in the pure state of being.
3. True Nature: You connect with your true nature, which is the awareness behind all experiences, leading to a sense of peace and clarity.

Practically, this might involve:

• Noticing the Noticer: Instead of just observing thoughts, notice the part of you that is observing. This is the awareness.
• Resting in Awareness: Allow yourself to rest in this state of pure awareness without trying to change or judge anything.
• Regular Practice: Integrate this practice into your daily life to gradually shift from being entangled in thoughts to residing in pure awareness.

In essence, being aware of awareness is about shifting your focus from the content of your experience to the context, the background awareness in which all experiences unfold. This can lead to a profound sense of inner peace and freedom.
