The word compassion comes from Buddhism, the avalokitesvara bodhisattva with great compassion. If we don't interpret the word "compassion", we will have the meaning of harmony between suffering and pleasure, and we will interpret three kinds of compassion: life (sentient beings have feelings), dharma and no chance. I simply explain as follows:

Bitter and bittersweet

(1) Bitterness and pleasure: There are two theories: one is that bitterness is good, and joy is sadness; Second, happiness is kindness, and pain is sadness. Regarding the former, there are fourteen clouds in the southern version of Nirvana Sutra (Dazheng12.696a):' To destroy the interests of all beings is to be merciful and merciful; It is a great pity to want to have fun with all beings. "Scramble the Notes of Past Lives and write it down (Dazheng 40.842b):' Pulling out bitterness is kindness, and joy is sorrow, so pulling out all the sufferings of all living beings with kindness and staying away from anxiety with sorrow.' On the latter, such as "On Great Wisdom" Volume 27 (Dazheng 25.256b):' Great kindness is the joy of all beings; Great compassion pulls out all the sufferings of all living beings. On the Ten Places (Dazheng 26.134 A):' Kindness is the cause and effect of happiness; Sad people have the same cause and effect. "Others, such as the Mahayana Vipassana, Volume 1 and the Shunzheng Theory, Volume 79, all said the same thing. In this regard, various classics have their own explanations. The reason why Hua Yan Jing Explore the Secret is called ten times is because it has two meanings, namely, harmony and separation. According to the general theory, compassion has the meaning of pulling out bitterness and joy. According to different theories, each one belongs to the other. The fourteenth volume of the Mahayana Sutra says that kindness and sorrow are not resentful, but are divided into two parts with different four meanings. One is different functions, so sadness can pull out suffering, and kindness can make you happy; Second, patients are treated in different ways, so sadness stops hurting and compassion stops greed. In addition, sadness can eliminate subtle anger, and kindness can send heavy anger; Third, because of different realms, all beings have many reasons for sadness and pain, but no reasons for happiness. The four rewards are different, so the sadness is empty and the grace is full. It's a symbol of compassion.
