The sails were scarcely spread, when a north wind arising, the air cleared up, and the sea was immediately calmed.  So that in thirteen days sailing, they arrived at the port of Sancian, where the Portuguese merchants of the ship had traffic.  As the season of sailing in those seas was already almost past, there were remaining but two ships of the Indies in port, one of which belonged to James de Pereyra.  The ship of Edward de Gama not being in condition to go on directly for Malacca without stopping by the way, and having need of refreshment at Sian, the saint went into the ship of his friend Pereyra.  It was wonderful, that at the same moment when he passed into that vessel, the wind, which for the space of fifteen days had blown at north, which was full in their faces who were going for the Indies, came about on the sudden; so that the day following, which was the last of the year 1551, they set sail again.  Another ship, which was waiting also for a wind, set out in their company; but that vessel found afterwards to her cost, that she carried not the apostle of the Indies.

Before they put to sea, Xavier discoursing with the pilot concerning the dangers of the ocean, (it was the same pilot who had brought him from Japan, whose name was Francis D’Aghiar,) foretold him, that he should not end his days upon the water; and that no vessel wherein he should be should suffer shipwreck, were the tempest never so outrageous.  D’Aghiar was possessed with so firm a belief of what the Father told him, and afterwards found the effect of it so manifest on various occasions, that, without observing either winds or seasons, he often put to sea in an old crazy vessel, ill provided; insomuch, that they who were ignorant of the secret cause of this his confidence, took him for a rash presuming man, and of little understanding in sea affairs.

Once, amongst many other times, he gave a demonstration how much he relied on the promise of the saint, and that was, in going from Tenasserim to the kingdom of Pegu, in a light barque, which was quite decayed, and out of order.  A tempest rising in the midst of his voyage, dashed against the rocks, and split in pieces some great vessels, which were following the barque of D’Aghiar.  She alone seemed to defy the rocks; and while the sea was in this horrible confusion, the pilot sat singing at his ease, as if the waters had been hushed beneath him.  A passenger, who shook with fear, demanded of him, “With what courage he could sing, when he was just upon the brink of death?” “It is because I fear nothing,” replied Aghiar:  “And I should fear nothing,” added he, “though the waves should mount as high again as now we see them, and my barque were also made of glass; for the Father Master Francis has assured me, that I should not die upon the seas, in whatsoever vessel I should go.”  Some Saracens who were in the barque, and who heard these sayings of the pilot, were so moved with this continued miracle, that they vowed to become Christians so soon as ever they should come on shore; and they complied religiously with their promise.  The barque casting anchor at Tanar, they received baptism at that place; so much the more persuaded both of the truth of the miracle, and of the Christian faith, because they saw before their eyes, upon the coast, the wrecks of other vessels, which were floating round about it.
