Vigorous in Chinese / Japanese...

精進 is a wide-ranging word that is used in Chinese, Japanese, and Korean.

It can mean devotion, diligence, concentration, aggressive, enterprising, vigorous, energetic, purification, pushing, asceticism, assiduity, or virility. 精進 is deep, and these two characters can express ideas that take a full English phrase to describe, such as “concentration of mind,” “to forge ahead vigorously,” or “to dedicate oneself to progress.”

Used in the context of Buddhism, it means “making earnest efforts to cultivate virtue and get rid of evil” or “zeal in one's quest for enlightenment.”

老當益壯 is a Chinese proverb that means “old but vigorous” or “hale and hearty despite the years.”

Said of someone who is more spirited when he/she grows older.

The story behind this Chinese proverb:

In the Eastern Han Dynasty, there was a man named Ma Yuan. He had been planning to herd animals on the frontier since he was young. When he grew up, Ma became a minor official of a county.

Once, he was sending some prisoners to another location. He felt pity for them, so he set them free, and then he fled to another county in the north. He herded animals there, and thus his dream came true. He always said: “If you want to be a great man, the poorer you are, the firmer in spirit you have to be; the older you are, the more spirited you should be.”

Later, when he was even older, Ma Yuan became a famous general of the Eastern Han Dynasty and contributed to many battles.

This “strong” character is the more “healthy” version of strong. 健 is the “strong” that is appropriate for an athlete.

Beyond “healthy,” it can also mean strength, persistence, vigorous, or invigorated/invigoration.

This word closely matches the way initiative is often used in English. This word can also mean active, energetic, vigorous, positive (outlook), or proactive in Chinese.

The meaning also includes positive and progressive in Japanese and Korean.

健やか is a verbose way to say strong and healthy in Japanese. 健やか is the “strong” that is appropriate for an athlete.

Beyond “healthy,” it can also mean strength, persistence, vigorous, or invigoration.

Japanese also use the first Kanji to mean the same thing. This version adds two hiragana which serve to emphasize or amplify the word and clarify the meaning.

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

理直氣壯 is a Chinese proverb that means “to do something while knowing you’re in the right.”

This can also be translated as and is appropriate when you are:

“In the right and self-confident”
“Bold and confident with justice on one's side”
“Having the courage of one's convictions”
“Justified and forceful”
“To be confident and vigorous because reason and logic are on one's side”
“Justified and confident”

This Japanese proverb can be translated as “flourish and wither, prosper and perish,” “life is full of fortune and misfortune,” or simply “vicissitudes of life.”

栄枯盛衰 / 榮枯盛衰 is about the rise and fall of human affairs or the ups and downs of life. Prosperity comes and goes, everything is fleeting and temporary, but like waves, another swell of prosperity may come.

Here's how the Kanji break down in this proverb:

栄 = prosper; thrive; flourish; boom.
枯 = wither; die.
盛 = prosperous; flourishing; thriving; successful; energetic; vigorous; enthusiastic.
衰 = become weaker; decline; get weak; die down; subside; abate; fail.

Notes: The original version of the first character looks like the image to the right. In modern Japan, they simplified that Kanji a bit into the version shown above. If you have a preference for which style is used for your calligraphy, please let me know when you place your order.

Apparently, with that original version of the first character, this is also used in Korean Hanja. However, I have not confirmed that it’s used in the same way or is widely-known in Korean.
