The awful things that we say to ourselves - about regrets, failures, disappointments, assaults, etc. - are bound to make us feel bad. What a way to live! In our minds we continue to hope for a better past, as if thinking could make the past better. Frustration with the way things are produces obsessive thinking.
NEXT. . . . . . . . For [Nature] can so inform
The mind that is within us, so impress
With quietness and beauty, and so feed
With lofty thoughts, that neither evil tongues,
Rash judgments, nor the sneers of selfish men,
Nor greetings where no kindness is, nor all
The dreary intercourse of daily life
Shall e'er prevail against us or disturb
Our cheerful faith that all which we behold
Is full of blessings.
