Importance of Metta.
by Friends of Godwin
In Buddhism, meditation on loving-kindness has a very important place. The words loving-kindness are a translation of the Pali word metta, which means friendliness. There is an interesting quotation from the Buddha about the importance of metta. He was talking to a group of monks and he told them that if they could practice loving-kindness even for the time that it would take to snap their fingers, they would be worthy of being monks.
To my mind this has two important implications or two meanings. One is that even if you practice loving-kindness for just a few moments, that is good enough. The other is that it shows the importance of developing loving-kindness.
