Metta is the most important thing should be cultivated or practiced. According to persons, there are so many metta such as Lord Buddha’s metta, parents’ metta, teachers’ metta, my metta and your metta etc. If metta is practiced by everyone, the world would be very peaceful. The following paragraphs will be mentioned what the Buddha taught on metta, the history of mettasuttara and how metta is should be developed. As matter of fact, it is not easy to practice metta by correcting way but we ourselves should try to practice. It is easier to practice metta by going to any meditation center than staying at home or at work. If we are frightened by ghosts, we must radiant our metta deeply. For example, when some Myanmar people were frighten by some ghosts on the ship then they recited some verses such as mettasuttara, pathana and paritta etc.
