Why is the Buddha an "emblem of solitude and poverty"?
Buddha was no hermit. After his enlightenment experience he made it his life's mission to travel around India teaching his philosophy to as many people as would listen.
And he certainly didn't advocate poverty. He tried life as an ascetic and rejected it, instead preferring The Middle Way, in between self denial and self indulgence.
And the whole cactus and books policing is beyond parody.
