People ask: "Why the Buddhist put their palms together and say to each other 'Amituofo' once they meet? What does that mean?"
This is a very good question. Amituofo (Amitabha Buddha) is a kind of blessing from Sanskrit, an ancient Indic Language. It means, in our modern words, wish you infinitude of life-span and brightness.
Such a blessing actually has deeper implications. It reminds us that in our lifetime, we need brightness, infinitude of brightness and we have to be straight and selfless towards all beings in the world. Such implication is very important to us, each time we hear the words, we shall remind ourselves of that.
