In the simplest terms, 愛語 means kind words.

In the Buddhist context, this is one of the four methods of approach to people which the bodhisattvas use to guide them to the way of the Buddha.

Other translations include loving speech or simply the words of a bodhisattva.

愛語 is also a common female name, Aigo, in Japanese.

These two characters mean compassion and sympathy in Chinese, Japanese, and Korean, which makes this word universal.

Compassion is caring and understanding someone is hurt or troubled (even if you don't know them). It is wanting to help, even if all you can do is listen and say kind words. You forgive mistakes. You are a friend when someone needs a friend.

仁恕 is a word in Chinese and Japanese that means something like benevolence with magnanimity or kindness with a forgiving nature.

If this describes you, then you are the type of person that I would like to call my friend.

Note: 仁恕 is not commonly used in Korean.
