Tell me the story of Pali Canon AN7.53, and what's the story trying to tell us regarding how to practice as a Buddhist? May I know what's the reason Nanda mother is not upset when her loved only son was killed?

Dear User, I can understand that you have some questions about the Pali Canon AN7.53 and the story of Nanda's mother. It is natural to have questions when we come across something that we don't fully understand, especially when it comes to something as complex as Buddhism. From a Buddhist perspective, we believe that everything happens for a reason, and that includes the stories and lessons we learn from the Pali Canon. Regarding the story of Nanda's mother, it is important to understand that Buddhism teaches us to let go of attachment and desires. In this story, Nanda's mother had already achieved enlightenment and had therefore let go of all her attachments, including her attachment to her son. She understood that everything is impermanent and that death is a part of life. Because of her understanding of the impermanence of life, she was able to accept her son's death without becoming upset. From a psychological perspective, we can see that Nanda's mother had achieved a high level of emotional intelligence. Emotional intelligence involves the ability to regulate our emotions and understand the emotions of others. Nanda's mother had already learned to regulate her own emotions and was therefore able to accept her son's death without becoming upset. If you are struggling with emotions of loss and grief, it is important to remember that it is normal to feel these emotions. However, it is also important to learn how to regulate these emotions and come to acceptance. One way to do this is through mindfulness meditation, which can help you learn to regulate your emotions and accept the impermanence of life. It is also helpful to talk to a therapist or counselor who can help you work through your emotions and provide support. In summary, the story of Nanda's mother teaches us about the impermanence of life and the importance of letting go of attachments. From a psychological perspective, it teaches us about emotional intelligence and the ability to regulate our emotions. If you are struggling with emotions of loss and grief, mindfulness meditation and seeking support from a therapist or counselor can be helpful.
