The Tathataga-King whose Wisdom Freely Penetrates the Mountains and Seas. This is the name that a^nanda will have in his future incarnation as a buddha, according to the prediction made in the Lotus Sutra by S/a^kyamuni. In the 人记 chapter of the Lotus Sutra it says: "佛告, 阿难, 汝于来世当作佛. 号山海慧自在通王如来." Also see Leon Hurvitz: Scripture of the Lotus Blossom of the Fine Dharma, p. 168. Here Ra^hula and a^nanda somewhat selfishly and vainly nag the Buddha to give predictions for them, since he has given predictions of Buddhahood for the others present at the assembly.[法华经 T 262.9.29c6]
