The miracle of the "double appearances”. When the Buddha laid down a rule forbidding the exercise of supernatural powers by monks - following on the miracle performed by Pindola Bháradvája (q.v.) - the heretics went about saying that henceforth they would perform no miracles except with the Buddha. Bimbisára reported this to the Buddha, who at once accepted the challenge, explaining that the rule was for his disciples and did not apply to himself. He, therefore, went to Sávatthi, the place where all Buddhas perform the Miracle. In reply to Pasenadi, the Buddha said he would perform the miracle at the foot of the Gandamba tree on the full moon day of Asálha. This was in the seventh year after the Enlightenment (DA.i.57).
The heretics therefore uprooted all mango trees for one league around, but, on the promised day, the Buddha went to the king's garden, accepted the mango offered by Ganda, and caused a marvelous tree to sprout from its seed. The people, discovering what the heretics had done, attacked them, and they had to flee helter skelter. It was during this flight that Púrana Kassapa (q.v.) committed suicide. The multitude, assembled to witness the miracle, extended to a distance of thirty six leagues. The Buddha created a jewelled walk in the air by the side of the Gandamba. When the Buddha's disciples knew what was in his mind, several of them offered to perform miracles and so refute the insinuations of the heretics. Among such disciples were Gharaní, Culla Anátthapindika, Círá, Cunda, Uppalavanná and Moggallána.
The Buddha refused their offers and related the Kanhausabha and Nandivisála Játakas. Then, standing on the jewelled walk, he proceeded to perform the Yamaka-pátiháriya (Twin Miracle), so called because it consisted in the appearance of phenomena of opposite character in pairs - e.g., producing flames from the upper part of the body and a stream of water from the lower, and then alternatively. Flames of fire and streams of water also proceeded alternatively from the right side of his body and from the left. DA.l.57; DhA.iii.214f. explains how this was done. From every pore of his body rays of six colors darted forth, upwards to the realm of Brahmá and downwards to the edge of the Cakkavála. The Miracle lasted for a long while, and as the Buddha walked up and down the jewelled terrace he preached to the multitude from time to time. It is said that he performed miracles and preached sermons during sixteen days, according to the various dispositions of those present in the assembly. At the conclusion of the Miracle, the Buddha, following the example of his predecessors, made his way, in three strides, to Távatimsa, there to preach the Abhidhamma Pitaka to his mother, now born as a devaputta.
The Twin Miracle is described at DA.i.57, and in very great detail at DhA.iii.204; see also J.iv.263ff. The DhA. version appears to be entirely different from the Játaka version; the latter is very brief and lacks many details, especially regarding Pindola's miracle and the preaching of the Abhidhamma in Távatimsa. The account given in Dvy. (143-66) is again different; the Miracle was evidently repeatedly performed by the Buddha (see, e.g., Candanamálá), and it is often referred to - e.g., J.i.77, 88, 193; Ps.i.125; SNA.i.36; AA.i.71; MA.ii.962; Mil. 349; Vsm.390; PvA.137; Dáthávamsa i.50. The miracle was also performed by the Buddha's relics; see, .e.g., Mhv.xvii.52f.; Sp.i.88, 92.
It is said (Mil.349) that two hundred millions of beings penetrated to an understanding of the Dhamma at the conclusion of the Miracle.
The Twin Miracle can only be performed by the Buddha. Mil.106.
