"The subject here is of course loving kindness (metta). Usually the practice of the four divine abidings (brahma vihara) are taken together. They all have a being/beings as the object, or we may say that they are all a positive mental relationship for one or a group of beings.
This form of meditation is especially suitable for those who intend to overcome anger or anger-related problems (e.g. bad temper, jealousy, cruelty, fear, worry and anxiety).
It is also very practical as it creates good relationship between and among people. This makes life and work in society easy and happy. This meditation is also generally suitable for beginners for it brings quick results. It has been said, for one with metta, the mind calms quickly. It is also fairly safe without much complication. Hence metta is one of the tranquillity meditations recommended for beginners."
