Humans born in this world are social, interact with each other, newborns definitely need help, namely a mother and it is not possible for the baby to immediately find food and drink alone. This continues until the baby continues to grow into a teenager until now, as we do today.
Humans cannot live alone because they need each other, give and receive.
To be harmonious in this life we are obliged to do good and help each other, many things we can do include:
I have done it, whatever I do is sincere because of the social nature of humans and I do not expect personal benefits from it, hopefully what we do in this life can benefit many people.
Have a nice day.
