Zen Heart Zen Mind in Chinese / Japanese...

禪心 represents an image of your meditation coming from and filling your heart.

The meaning of the first character is “meditation” and the second character is usually defined as “heart” or sometimes “mind.”

There is a two-fold meaning here, as a good meditation session must start with a centered heart or mind. Yet at the same time, meditation serves to cleanse, focus, and center the heart and mind.

安心 can be defined as relief, peace of mind, feeling at ease, to be relieved, to set one's mind at rest, and easiness.

安心 is a nice word that encompasses great meanings within just two characters. Some of the other meanings include pacifying, settling the mind, and peace of mind. It's also the idea of feeling a sense of security, safety, and confidence in your state of well-being.

This can be used by everyone, but some consider it to be a Buddhist concept (You'll find it in your Zen dictionary).

Note: Can be romanized as Anshin or Anjin in Japanese.

In Japanese, 無心 means innocent or without knowledge of good and evil. It literally means “without mind.”

無心 is one of the five spirits of the warrior (budo) and is often used as a Japanese martial arts tenet. Under that context, places such as the Budo Dojo define it this way: “No mind, a mind without ego. A mind like a mirror which reflects and dos not judge.” The original term was “mushin no shin,” meaning “mind of no mind.” It is a state of mind without fear, anger, or anxiety. Mushin is often described by the phrase “Mizu no Kokoro,” which means “mind like water.” The phrase is a metaphor describing the pond that clearly reflects its surroundings when calm but whose images are obscured once a pebble is dropped into its waters.

This has a good meaning in conjunction with Chan / Zen Buddhism in Japan. However, out of that context, it means mindlessness or absent-mindedness. To non-Buddhists in China, this is associated with doing something without thinking.
In Korean, this usually means indifference.

Use caution and know your audience before ordering this selection.

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.

悕望の心 is “Kemō no Shin,” a Japanese Zen Buddhist word that means “The seeking mind” or “[Having] The mind to seek something.”

The first two characters mean longing for. The last two mean “of mind” or “of heart.” So, this is a mind that longs for or seeks knowledge, etc.
