Things are looking bad

Nothing but the shirt on your back

to stand with arms and legs spread; to open up your feelings

A good child must be brought up by a good mother

An empty theory

Outside your field of expertise

sharply, suddenly

sailfin sandfish

Unstoppable momentum

Like someone poked a hornet nest

beautiful from any angle; a pure and beautiful heart

one person doing the work of many

remaining hopeful

a sage living the hermit's life, unrecognized by society

Time flies

running rampant

postscript

the entire world

going through many hardships

traversing great distances; crossing mountains and rivers
