How does Louis Fischer use imagery in Gandhi?

Imagery:

"Mahatma Gandhi's body lay on the pyre with his head to the north. In that position Buddha met his end." (7)

"Winston Churchill saw this better than anyone. He was revolted, he declared, by 'the nauseating and humiliating spectacle of this one-time Inner Temple lawyer, now seditious fakir, striding half-naked up the steps of the Viceroy's palace, there to negotiate and parley on equal terms with the representative of the King-Emperor.'"(10)

"Gandhi had the answer and antidote to Stalinism: a big, brave, spirit-over-matter individual who could resist invasions of his freedom because he put principles above possessions. This prescription would defeat communism and cure democracy." (88)
