According to Buddha, the root cause of suffering is attachment . The symbol of pig (ignorance), snake (aversion) and the rooster (affection) binds a man to Maya and suffering. The default mode of life is ‘dukkha’ and the only goal of the man is to reduce his suffering and not chasing happiness. The image of Buddha walking through the attachment evokes same sentiments as the the tightrope walker in the first chapter of ‘thus spoke Zarathustra’ by Neitzche. That’s why he is the supreme overman (Ubermensch).
