As a prince of the Sakya people, Sakyamuni lived a luxurious life in the palace. One day, when he came outside the city and saw the suffering of old age, illness, and death, the prince decided to give up his luxurious life and pursue spiritual practice for enlightenment. It is said that the prince rode his favourite horse out of the city in the middle of the night and left without saying goodbye. The three Gandhanra, flying in the blue sky, watched him leave. This led to his fate of becoming a Buddha. Although the Buddhist picture painted by Hirayama Ikuo was based on the famous events in Sakyamuni's life, He reinterpreted these events with his conception of freedom. Through this unique imagination and the solemn color with the tone of ultramarine and green, it opened up a unique painting scene.
