This being the first open schism, one disruption after another took place among the Buddhistic Order. There were many different schools of the Buddhists at the time when King Acoka ascended the throne (about 269 B.C.), and the patronage of the King drew a great number of pagan ascetics into the Order, who, though they dressed themselves in the yellow robes, yet still preserved their religious views in their original colour. This naturally led the Church into continual disturbances and moral corruption. In the eighteenth year of Acoka's reign the King summoned the council of 1,000 monks at Pataliputra (Patna), and settled the orthodox doctrine in order to keep the Dharma pure from heretical beliefs. We believe that about this time some of the Buddha's preachings were reduced to writing, for the missionaries despatched by the King in the year following the council seem to have set out with written sutras. In addition to this, some of the names of the passages of the Dharma are given in the Bharbra edict of the King, which was addressed to the monks in Magadha. We do not suppose, however, that all the sutras were written at once in these days, but that they were copied down from memory one after another at different times, because some of the sutras were put down in Ceylon 160 years after the Council of Patna.

In the introductory book of Ekottaragama (Anguttara Nikaya), now extant in the Chinese Tripitaka, we notice the following points: (1) It is written in a style quite different from that of the original Agama, but similar to that of the supplementary books of the Mahayana sutras; (2) it states Ananda's compilation of the Tripitaka after the death of the Master; (3) it refers to the past Buddhas, the future Buddha Maitreya, and innumerable Bodhisattvas; (4) it praises the profound doctrine of Mahayanism. From this we infer that the Agama was put in the present form after the rise of the Mahayana School, and handed down through the hand of Mahasanghika scholars, who were much in sympathy with Mahayanism.

Again, the first book of Dirghagama, (Digha Nikaya), that describes the line of Buddhas who appeared before Shakya Muni, adopts the whole legend of Gotama's life as a common mode of all Buddhas appearing on earth; while the second book narrates the death of Gotama and the distribution of his relies, and refers to Pataliputra, the new capital of Acoka. This shows us that the present Agama is not of an earlier date than the third century B.C. Samyuktagama (Samyutta Nikaya) also gives a detailed account of Acoka's conversion, and of his father Bindusara. From these evidences we may safely infer that the Hinayana sutras were put in the present shape at different times between the third century B.C. and the first century A.D.
