One who performs his duty without attachment, surrendering the results unto the Supreme Lord, is unaffected by sinful action, as the lotus leaf is untouched by water.
The best people you can have friends as are those who are detached.
Compassion without detachment is attachment to the bodily platform.
In order to have simplicity of mind one must have simplicity of life style, which means one must be detached from gain or loss, pleasure or pain, honor or dishonor, happiness or distress. One must simply be seeking purification of consciousness.
Detachment to material world can only come when we replace it with attachment for Krishna.
