The quote emphasizes the idea of being aware of one's thoughts without becoming overwhelmed by them. When your mind is busy with thoughts and distractions, it's important to step back and observe this mental activity. Rather than getting caught up in what you're thinking, acknowledging it as just a momentary experience can help maintain a sense of calm.
This perspective encourages mindfulness, teaching individuals to recognize that thoughts are transient and not definitive of one’s self. By observing the nature of mental activity, a person can cultivate a clearer understanding of their inner workings, leading to greater clarity and emotional stability.
