"知恵を得る方法は三つあります。一つ目は反映であり、これが最も高い方法です。二つ目は模倣であり、これが最も簡単な方法です。三つ目は経験であり、これが最も苦い方法です。"

Simplified Meaning:

Gaining wisdom can be done in three ways. The best way is to think deeply about things, like when someone takes time to understand their feelings and actions or learn from books and teachings. Another way, which isn't too hard, is to copy or follow the examples of wise people. For instance, a student might follow their teacher's advice without fully understanding it but still benefits from it. The last way, which is often the hardest, is learning from personal experience, especially mistakes and failures. Imagine a person who touches a hot stove and gets burned; they learn a valuable lesson, but it comes with pain. To apply these methods, one should take time to think about their actions, look up to role models, and be ready to learn and grow even from tough experiences.
