Heart of the Buddha in Chinese / Japanese...

佛心 means the Buddha's mind, Buddha-heart, or the spiritually enlightened heart/mind.

The Buddha Heart is detached from good and evil and other such constructs. The Buddha Heart has mercy, compassion, and loving-kindness for all sentient life, the good, the wicked, and all in between.

The heart and mind (心) are the same concepts in the ancient Orient, so you can use heart and mind interchangeably in this context.

心光 can mean the light from a Buddha's mind or “merciful heart.”

This would especially be the light emanating from Amitābha.

Note that the character 心 can mean mind or heart. 光 means light or brightness - but in this context can suggest a glow of mercy or compassion. This can also be a Japanese surname that is romanized as Shinkou or Shinko.

聖心会 is the Japanese martial arts title “Seishinkai” or “Seishin-Kai.”

It literally means “Sacred Heart Association” or “Pure-Heart Club.”

聖 can mean holy, sacred, saint, sage, virtuous, expert, wise and good, upright, or correct.
心 can mean heart, mind, center, core, spirit, soul, or vitality.

聖心 creates a word meaning sacred heart, or the holy mind (that of Buddha).
会 in Japanese means association, club, meeting, assembly, party, gathering, conference, athletic meet, or society.

In Zen Buddhism, 本心 means “original mind” or “original heart,” which refers to one's Buddha-nature present from birth.

This can also be translated as true feelings, real intention, one's own heart, one's right mind, one's senses, one's conscience, or fundamental mind.

Note: 心 can mean heart or mind - thought in ancient Asia to be the same organ.

菩提心 means Bodhi-mind or Bodhi-heart.

This title represents the will to realize supreme enlightenment. The awakening of the Bodhi-mind is of utmost importance in Buddhist training.

Other definitions include the mind for or of bodhi, the awakened, enlightened mind, or having Buddha-nature.

人間性を再生するのは寛容な心親切な言葉奉仕と思いやりの精神 is known as the Triple Truth of Buddhism in Japanese.

The Buddha ordered that all should know this triple truth...
A generous heart, kind speech, and a life of service and compassion are the things that renew humanity.

That is the English translation most commonly used for this Japanese Buddhist phrase. You might have seen this on a coffee cup or tee shirt.

Note: Because this selection contains some special Japanese Hiragana characters, it should be written by a Japanese calligrapher.

The first Kanji alone means to wash, bathe, primness, cleanse or purify.

The second Kanji means heart, mind, soul, or essence.

Together, these two Kanji create a word defined as “purified spirit” or “enlightened attitude” within Japanese martial arts.

洗心 is one of the five spirits of the warrior (budo) and is often used as a Japanese martial arts tenet. Under that context, it's often defined as a spirit that protects and harmonizes the universe. Senshin is a spirit of compassion that embraces and serves all humanity and whose function is to reconcile discord in the world. It holds all life to be sacred. It is the Buddha mind.

This title will only be familiar to Japanese who practice certain martial arts. Others may not recognize this word at all.

洗心 does not show up as a word in too many Chinese dictionaries, but it can be read and has the same meaning in Chinese.

There is an issue with the first character. The original, and probably most correct version is shown above. However, many dojo documents and other sources have used a more simple first character. Arguments ensue about which version is correct. If you want to be correct in the Japanese language, use the "Select and Customize" button above. If you want to match the Kanji used by your dojo, click the Kanji shown to the right. There is a slightly different meaning with this first character which means before, ahead, previous, future, precedence.
