"ほとんどの人は外界の観察に熱中するあまり、自分の内面で何が起こっているのか全く気付かない。"

Simplified Meaning:

People often get so caught up in what's happening around them that they forget to pay attention to their own thoughts and feelings. It's like someone who is always on their phone, checking social media, and never taking time to think about what they really want or how they feel. This can lead to being out of touch with oneself and making decisions that don't make us happy. For example, if someone is constantly worried about what their friends think and tries to keep up with their lifestyle, they might never pause to consider if they really enjoy it or if it brings them joy. They might end up feeling lost or unfulfilled because they haven't taken the time to understand their own desires and needs. To avoid this, it's important to sometimes step back from the busy outside world and spend time reflecting on ourselves. This might involve journaling, meditating, or simply thinking about our goals and emotions. By doing this, we can make better choices that align with who we truly are and what makes us happy. This reflection can lead to a more satisfying and authentic life.
