The meaning of mettæ might come into different interpretations depending on several contexts and situation. When the mettæ is within only family members and relatives, it is named love (pema), when it is common to all without any differentiations, it is known loving-kindness. Sometimes, it is involved in social events such as releasing birds and animals, helping the elders and others in need of help, and contributing the assistance to anyone else. Sometimes it is confused between mettæ and pema due to which mettæ is accused of bias.
The practice of vegetarianism, the practice of meditation and gaining protection by cultivating mettæ, etc, are embodied in the general functions of mettæ. Even though mettæ has many functions, its reality and identity is not changeable, that is: selfless love, altruistic love, benevolence, friendliness, welfare, peace and real happiness.
