Four pairs of polar opposites are identified as "mundane" concerns.
One is defiled by the mundane concerns if one's motivation derives from:
Attachment to gain, or fear of loss.
Attachment to pleasure, or fear of pain.
Attachment to renown, or fear of infamy.
Attachment to praise, or fear of blame.
