After entering Sage Mode, Hashirama creates a wooden statue of titanic proportions, easily able to dwarf a tailed beast like Kurama. Thousands of hands emanate from the statue's back in countless concentric rows, while its two main hands are clasped as if in prayer and it has numerous faces all around it's forehead. The statue is able to stand and move in order to attack on Hashirama's behalf.
This technique seems to be influenced by the Buddhist bodhisattva of compassion, Avalokiteśvara, also known as "Senju Kannon" (千手観音, Thousand-Armed Kannon).
One prominent story tells of Kannon vowing never to rest until he had freed all beings from Saṃsāra. After strenuous effort, but struggling to comprehend the needs of so many who still had yet to be saved, his head splits into eleven pieces. The Buddha Amida, seeing his plight, gives him eleven heads with which to hear the cries of the suffering. Upon hearing and comprehending these cries, Kannon attempted to reach out to all those who needed aid, but found that his two arms shattered into pieces. Once more, Amida comes to his aid and grants him a thousand arms with which to aid the suffering.
