In Nichiren Buddhist Gohonzons, the two Buddhas are shown forming the anjali mudra (Japanese, gassho-in), the hand gesture in which both palms are placed together in front of the heart to indicate an attitude of praise and reverence. This is the same mudra that Nichiren Buddhist practitioners use when chanting the Odaimoku. It is unusual for Buddhas to be shown making this mudra, but in this case it indicates that both Shakyamuni Buddha and Many Treasures Tathagata have come together to praise the Wonderful Dharma of the Lotus Flower Sutra to which they have awakened and to praise the Buddha nature in all sentient beings.
