Niō (仁王) or Kongōrikishi (金剛力士) are two wrathful and muscular guardians of the Buddha standing today at the entrance of many Buddhist temples in East Asian Buddhism in the form of frightening wrestler-like statues. They are dharmapala manifestations of the bodhisattva Vajrapāṇi, the oldest and most powerful of the Mahayana Buddhist pantheon. According to Japanese tradition, they travelled with Gautama Buddha to protect him and there are references to this in the Pāli Canon as well as the Ambaṭṭha Sutta. Within the generally pacifist tradition of Buddhism, stories of dharmapalas justified the use of physical force to protect cherished values and beliefs against evil. The Niō are also seen as a manifestation of Mahasthamaprapta, the bodhisattva of power that flanks Amitābha in Pure Land Buddhism and as Vajrasattva in Tibetan Buddhism.
