Not Eternal in Chinese / Japanese...

不老 is a Japanese word that means “perpetual youth” or “forever young.”

It contains the idea of never getting old. It literally means “never aging,” or “not [getting] old.”

不來不去 is a Buddhist term, originally anāgamana-nirgama from Sanskrit.

This implies that things are neither coming into nor going out of existence.

This can also mean “all things are eternal,” or others will call this the Buddhist concept of the eternal conservation of energy.

This theory predates Albert Einstein and Isaac Newton.

Note: 不來不去 is not a well-known word for both Buddhists and non-Buddhists, so not all will recognize it.

無限大の愛 is a Japanese title meaning infinite great love, unlimited great love, or eternal love.

無 means never, not, or like a prefix “un-.”

限 means limited, restricted, or bound.
大 means great or big.
の is a possessive article.
愛 means love or affection.

無限愛 is the Chinese and Japanese title meaning infinite love, unlimited love, or unbounded love.

The first character means never, not, or like the prefix “un-.”

The second means limited, restricted, or bound.

The third means love or affection.

永生 are the last two words from John 3:16 in the Chinese Union Bible.

Although not specifically Christian, this is the way to express ever-lasting life or eternal life in Chinese.

In Japanese, this can either mean eternal life or immortality.

This text is the first chapter of the Daodejing / Tao Te Ching.

The text reads:
道可道、非常道。名可名、非常名。 無名天地之始 有名萬物之母。故常無欲以觀其妙、常有欲以觀其徼。此兩者同出而異名。同謂之玄。玄之又玄、衆妙之門。

This classical Chinese passage comes from the Mawangdui (馬王堆帛書) text.

The first character means “eternal” or “forever,” and the second means “not” (together, they mean “never”). The last two characters mean “give up” or “abandon.” Altogether, you can translate this proverb as “never give up” or “never abandon.”

Depending on how you want to read this, 永不放棄 is also a statement that you will never abandon your hopes, dreams, family, or friends.

In the most basic translation, 中道 means road through the middle or middle road.

The expanded meaning can be moderation or the golden mean.

But if you are looking for this title, you are probably seeking the Buddhist definition, which is more complex.

中道 is the middle way or middle path of Buddhism. This has various interpretations. In general, it denotes the mean between two extremes and has special reference to the mean between realism and nihilism, or eternal substantial existence and annihilation.

The Buddha teaches that one should not take things to extremes. Don't be extremely evil and engage in debauchery and murder. But do not spend every waking out trying to be a perfect saint. Instead, take the middle path, try to help others, show loving kindness wherever you can, and try not to do harm. If you inadvertently harm another being, make amends if you can, and move on. Realize you are not perfect, but in time, a path of moderation lead toward proper living and enlightenment.

無常 is the state of being “not permanent,” “not enduring,” transitory, or evolving.

It can also mean variable or changeable. In some contexts, it can refer to a ghost that is supposed to take a soul upon death. Following that, this term can also mean to pass away or die.

In the Buddhist context, this is a reminder that everything in this world is ever-changing, and all circumstances of your life are temporary.
If you take the Buddhist philosophy further, none of these circumstances are real, and your existence is an illusion. Thus, the idea of the eternal soul is perhaps just your attachment to your ego. Once you release your attachment to all impermanent things, you will be on your way to enlightenment and Buddhahood.

Language notes for this word when used outside the context of Buddhism:
In Korean Hanja, this means uncertainty, transiency, mutability, or evanescent.
In Japanese, the definition orbits closer to the state of being uncertain.
