Buddha Shakyamuni explained these concepts more than 2,500 years ago. People do not believe them, though, and even label Buddhism “negative”, “pessimistic”, and so on. In the 21st century, there are many people who do not have problems with food and clothing and even possess great wealth. Thus, we now can see what happened in the current situation.
We must learn to let go of this outrageous selfishness. Otherwise, we will encounter mental problems. If our whole life is driven by vanity, we will never have happiness. Ordinary people cannot immediately put aside all selfishness, but if we are interested in how to let go of selfishness, Mahayana Buddhism provides us with many methods. If we train ourselves in Mahayana Buddhist philosophy and its practical methods, we will gradually become someone who is concerned for others and shares their happiness. This is what is called a bodhisattva.
