A pin has a head, but has no hair

What are heavy? sea-sand and sorrow. What are brief? today and tomorrow. What are frail? spring blossoms and youth. What are deep? the ocean and truth.

My heart is like a singing bird.

Who has seen the wind? Neither you nor I but when the trees bow down their heads, the wind is passing by.

The downhill path is easy, but there's no turning back.

It's surely summer. for there's a swallow: Come one swallow, his mate will follow, The bird race quicken and wheel and thicken.

Hope is like a hairball trembling from its birth.
