The Spirit of Dragon and Tiger in Chinese / Japanese...

龍虎精神 means the spirit of the dragon and tiger.

It speaks to the vitality and vigor that is the nature of these two creatures.

Beyond “spirit,” the last two characters can also mean mind, soul, or heart. Therefore, you can also say this means “Heart of the Dragon and Tiger,” etc.

龍虎精神 is often titled “Ryukoseishin” in many Japanese martial arts.

龍馬精神虎虎生威 is an old proverb that is used to wish someone great health and success combined as a great compliment.

The meaning is “The vigor and spirit of the legendary dragon-horse and the power and prestige of the tiger.”

By giving a wall scroll like this to someone, you were either wishing or telling them that they have these qualities. There is also a suggestion of good health - at least anyone with the vigor of a dragon horse would seem to also be in good health.
