He is the protector and guide of Gautama Buddha and rose to symbolize the Buddha's power. Vajrapāni is extensively represented in Buddhist iconography as one of the earliest three protective deities or bodhisattvas surrounding the Buddha. Each of them symbolizes one of the Buddha's virtues: Manjushri manifests all the Buddhas' wisdom, Avalokiteśvara manifests all the Buddhas' immense compassion, and Vajrapāni protects Buddha and manifests all the Buddha's power as well as the power of all five tathāgatas (Buddhahood of the rank of Buddha). Vajrapani is one of the earliest Dharmapalas of Mahayana Buddhism and also appears as a deity in the Pali Canon of the Theravada school. He is worshiped in the Shaolin Monastery, in Tibetan Buddhism and in Mahayana Buddhism (where he is known as Mahasthamaprapta and forms a triad with Amitābha and Avalokiteśvara). Manifestations of Vajrapāni can also be found in many Buddhist temples in Japan as Dharma protectors called Nio. Vajrapāni is also associated with Acala, who is venerated as Fudō-Myōō in Japan, where he is serenaded as the holder of the vajra.
