From R.H. Blyth:
“…when we think about ourselves, we are deeply conscious of our physical pains and pleasure, but if we forget ourselves, the body too, becoming one with the mind, is hardly aware of its pain and pleasure, cold and heat. How much our happiness depends upon the condition of our minds, is shown also in what Macbeth says,
‘Present fears
Are less than horrible imaginings.'”
