Emptiness in Chinese / Japanese...

This single character means empty, void, hollow, vacant, vacuum, blank, nonexistent, vacuity, voidness, emptiness, non-existence, immateriality, unreality, the false or illusory nature of all existence, being unreal.

In Buddhist context, this relates to the doctrine that all phenomena and the ego have no reality but are composed of a certain number of skandhas or elements, which disintegrate. The void, the sky, space. The universal, the absolute, complete abstraction without relativity. The doctrine further explains that all things are compounds, or unstable organisms, possessing no self-essence, i.e. are dependent, or caused, come into existence only to perish. The underlying reality, the principle of eternal relativity, or non-infinity, i.e. śūnya, permeates all phenomena making possible their evolution.

From Sanskrit and/or Pali, this is the translation to Chinese and Japanese of the title śūnya or śūnyatā.

In Japanese, when pronounced as "ron" (sounds like "roan") this can be a given name. It should be noted that this Kanji has about 5 different possible pronunciations in Japanese: kuu, kara, sora, ron, and uro. 空 is also an element in the Japanese version of the five elements.

According to Soothill 眞空妙有 means:
The true void is the mysteriously existing; truly void, or immaterial, yet transcendentally existing.

眞空妙有 is the state of being absolutely nonexistent after removing all errant worldly influences. 眞空妙有 is achieved when all forms of existence is seen for their real nature.

This is a complex Buddhist concept. Feel free to add to the conversation about this concept here: Asian Forum: Shinku Myou

虛空 means empty space, empty sky, or void.

In the Buddhist context, it can mean "emptiness of the material world". This can also be used as an adjective to modify other words with a meaning of unreal or insubstantial.

無 is the simple way to express "nothing".

However, this single character leaves a bit of mystery as to what you might really mean if you hang it as a wall scroll. I'm not saying that's a bad thing; as you can decide what it means to you, and you won't be wrong if you stay within the general context.

More info: 無 is usually used as a suffix or prefix for Chinese and Japanese words (also old Korean). It can be compared to "un-" or "-less" in English. It can also mean "not to have", no, none, not, "to lack", or nothingness.

In Japanese, first Kanji means "self-effacing", "humble oneself", "condescend", "be modest". The second means "void" or "emptiness".

謙虚 is the most common way to say humble or modest in Japanese without a derogatory meaning (some other words suggest weakness but this version holds a better humble meaning).

地水火風空 is the specifically-Japanese version of the five elements.

地水火風空 is a little different than the ancient or original Chinese version.

The elements are written in this order:
1. Earth / Terra / Ground
2. Water
3. Fire
4. Wind / Air
5. Sky / Emptiness / Void / Ether

Note: This set of Kanji can also be romanized as "ji sui ka fuu kuu", "jisuikafuukuu", or "jisuikafuku".

These can also be written in the order 地火風水空 (chi ka sui fuu kuu). Let me know when you place your order if you want the Kanji to be in this character order.
