what does this poem mean "the apology"???

Question

THINK me not unkind and rude
That I walk alone in grove and glen;
I go to the god of the wood
To fetch his word to men.
Tax not my sloth that I
Fold my arms beside the brook;
Each cloud that floated in the sky
Writes a letter in my book.
Chide me not, laborious band,
For the idle flowers I brought;
Every aster in my hand
Goes home loaded with a thought.
There was never mystery
But't is figured in the flowers;
Was never secret history
But birds tell it in the bowers.
One harvest from thy field
Homeward brought the oxen strong;
A second crop thine acres yield,
Which I gather in a song.

Answer 1

to me , it sounds like the person is apologizing for wandering off contemplating deep thoughts, while others are toiling away at physical labor,,,,,, he/she is saying that each thing they see/hear/touch, is bringing revelations to them,,,, it seems like the person has been doing this for a long time,,,,, threw two harvests
