Day 19 concludes Chapter 14, Peaceful Practices, and begins Chapter 15, The Appearance of Bodhisattvas from Underground.

Having last month considered the question poised by the Bodhisattva-mahāsattvas, more than eight times the number of the sands of the River Ganges, who had come from the other worlds, we witness the arrival of the Bodhisattvas from underground.

When he had said this, the ground of the Sahā-World, which was composed of one thousand million Sumeru-worlds, quaked and cracked, and many thousands of billions of Bodhisattva-mahāsattvas sprang up from underground simultaneously. Their bodies were golden-colored, and adorned with the thirty-two marks and with innumerable rays of light. They had lived in the sky below this Sahā-World. They came up here because they heard these words of Śākyamuni Buddha. Each of them was the leader of a great multitude. The Bodhisattvas included those who were each accompanied by attendants as many as sixty thousand times the number of the sands of the River Ganges. Needless to say, [they included those who were each accompanied by less attendants, for instance,] fifty thousand times, forty thousand times, thirty thousand times, twenty thousand times or ten thousand times the number of the sands of the River Ganges, or by attendants just as many of the sands of the River Ganges, or by attendants as many as a half, or a quarter of the number of the sands of the River Ganges, or by attendants as many as the sands of the River Ganges divided by a thousand billion nayuta, a billion, ten million, a million, ten thousand, a thousand, a hundred, ten, five, four, three or two attendants, or only by one attendant. [The Bodhisattvas] who preferred a solitary life came alone. The total number of the Bodhisattvas was innumerable, limitless, beyond calculation, inexplicable by any parable or simile.

Those Bodhisattvas who appeared from underground, came to Many-Treasures Tathāgata and Śākyamuni Buddha both of whom were in the wonderful stūpa of the seven treasures hanging in the sky. They [joined their hands together] towards the two World-Honored Ones, and worshipped their feet with their heads. Then they [descended onto the ground and] came to the Buddhas sitting on the lion-like seats under the jeweled trees, bowed to them, walked around them from left to right three times, joined their hands together respectfully, and praised them by the various ways by which Bodhisattvas should praise Buddhas. Then they [returned to the sky,] stood to one side, and looked up at the two World-Honored ones with joy. A period of fifty small kalpas elapsed from the Bodhisattva-mahāsattvas’ springing up from underground till the finishing of the praising of the Buddhas by the various ways by which Bodhisattvas should praise Buddhas. All this while Śākyamuni Buddha sat in silence. The four kinds of devotees also kept silence for the fifty small kalpas. By his supernatural powers, however, the Buddha caused the great multitude to think that they kept silence for only half a day. Also by the supernatural powers of the Buddha, the four kinds of devotees were able to see that the skies of many hundreds of thousands of billions of worlds were filled with those Bodhisattvas.
