What is Heart?

There is a heart carved in a cherry tree 
Sitting by the stream 
A volcano simply rests its head 
For the volcano is serene 

Two woman stand aside the tree 
One young, the other old 
The older one, more graceful 
The younger one, more bold 

The blossoms on the cherry tree 
Have an orange hue 
Throughout the seasons, the colors change 
There's red and pink and purple too  

A shrine sits in the distance 
Beneath a lavender field 
Although worn it is by aging 
Built it was by one who's skilled 

A junk is floating in the air 
A dragon's flying by 
Are they real or are they spirits? 
Or just clouds up in the sky?
