Analysis of Tz'u No. 16 (Bajiao)

Who planted the Bajiao tree under my windows?
Its shade fills the courtyard;
Its shade fills the courtyard...

Leaf to leaf, heart to heart,
  folding and unfolding,
It expresses boundless affection.

Sad and broken-hearted, lying awake on my pillow,
  Late into the night
    I hear the sound of rain.

It drips and splashes, cool and melancholy;
It drips and splashes, cool and melancholy....

Lonely for my beloved, grief-stricken,
  I cannot endure the mournful sound
    of rain.
