"誰もが悲しみを克服できるが、その悲しみを持っている者だけができない。"

Simplified Meaning:

When someone is going through a tough time, like losing someone important to them, others might think they understand and know what to do to feel better. It's easy for people who aren't feeling the pain to give advice and believe they know the right ways to cope. But the person who is actually suffering finds it much harder to deal with their own sadness. For example, imagine a friend who gets their dream job and another who gets fired on the same day. The friend with the new job might give advice on staying positive to the friend who got fired, but this is hard to follow when you are the one actually feeling the loss. It shows that we can't really know what someone else is going through emotionally, even if we think we do. The best way to apply this wisdom in life is to be compassionate and patient with those who are grieving, knowing that giving advice is different from truly understanding their pain.
