(六道仙人, Rikudō Sennin )
Saviour of this World (この世の救世主, Kono Yo no Kyūseishu )
God of Shinobi (忍の神, Shinobi no Kami )
D. According to Jiraiya , the Sage was a monk who appeared long ago in an age of endlesswar. He was the first to discover the truth of chakra , and with it he tried to lead the world to an era of peace instead of conflict. He travelled across the land, spreading his ideal and religion, the Shinobi Sect (忍宗, Ninshū ), which eventually came to be known as ninjutsu . His great deeds and ultimate desire to bring peace to the war-torn world made him widely known as the Saviour of this World (この世の救世主, Kono Yo no Kyūseishu ).
Centuries before the beginning of the main storyline, the sage defeated the most powerful demon in the ninja world, the Ten-Tails , and was praised as a god for the virtue of his victory. In order to protect the world from the Ten-Tails, the Sage developeda certain technique to seal the beast within his own body, giving him the ability to harness and control its overwhelming power; he became the first jinchūriki . However, this offered only a temporary solution. In the event of his death, the seal would break and the Ten-Tails would once again be unleashed upon the world

he was like father figure to all tailed beast and told that one day they will mingle to be one.
his apperance
Although initially depicted as a silhouette, several details about the Sage's appearance can be inferred. He had short hair that spiked up in the front with two distinctive pieces of hair resembling horns. He wore what appeared to be a cloak with a high collar, revealing his necklace with six red magatama . These symbols were later mimicked by Nagato 's Deva Path , and the seal around the neck of Naruto 's Nine-Tails Chakra Mode . On the back of his cloak was astylised Rinnegan with nine magatama in three rows beneath it. In one appearance where his face was partially visible, he was in an elderly state.this just easily simply he just pray at all times and descoverd the knowledge of chakras and spend most of his times preaching about peace just like Gautam Buddha who just preached about peace all the time till death.
