Absolute in Chinese / Japanese...

絶対的な力 is a long Japanese word that means, "Absolute Power".

By those terms, this is roughly the Japanese equivalent to "juggernaut".

This Buddhist title means, "The true way", "The true religion", "The way of the truth", or "The absolute Buddha-truth".

川蝉 is a common Japanese title for the kingfisher (Alcedo atthis).

There are a few ways to name this little greenish bird in Japanese, so be aware, this is not the only or absolute kingfisher title.

ジーザス is the name Jesus in Japanese.

ジーザス is a common version that approximates pronunciation in English. However, there are many variations for writing Jesus in Japanese, and it's hard to come up with an absolute answer (transliteration of names is more art than science).

Note: Because this title is entirely Japanese Katakana, it should be written by a Japanese calligrapher.

般若 means great wisdom or wondrous knowledge.

In the Buddhist context, this is prajna or prajñā, to know, to understand, to have the wisdom required to attain enlightenment.

Since this is a wisdom which transcends the realm of logic, the pure, absolute wisdom beyond the reach of words and concepts, it is not obtained through learning, but is realized for the first time through a religious experience.

勤勉 can be translated as diligence, industrious, assiduity, assiduous, diligent, or sedulity.

Diligence is working hard and doing your absolute best. You take special care by doing things step by step. Diligence helps you to get things done with excellence and enthusiasm. Diligence leads to success.

混沌 is the Japanese, Korean and Chinese word that means absolute confusion, disorder and chaos.

This more directly refers to primal chaos or primeval chaos.

When reading something about Chinese mythology, you may find this term used to describe the formless mass before creation.

Chinese scientists sometimes use this word to refer to the nebulous state before the universe was formed or nebulosity.

In some context, this could mean "a state of confusion".

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.

空無 is "nothingness" in a Buddhist context.

The first character means empty but can also mean air or sky (air and sky have no form).

The second character means have not, no, none, not or to lack.

Together these characters reinforce each other into a word that means "absolute nothingness".

I know this is a term used in Buddhism but I have not yet figured out the context in which it is used. I suppose it can be the fact that Buddhists believe that the world in a non-real illusion, or perhaps it's about visualizing yourself as "nothing" and therefore leaving behind your desire and worldliness.
Buddhist concepts and titles often have this element of ambiguity or rather "mystery". Therefore, such ideas can have different meanings to different people, and that's okay. If you don't get it right in this lifetime, as there will be plenty more lifetimes to master it (whatever "it" is, and if "it" really exists at all).

Soothill defines this as "Unreality, or immateriality, of things, which is defined as nothing existing of independent or self-contained nature".
