I went back each day for fifteen days, and each time, except one Monday and one Friday, the lady appeared and told me to look for a stream and wash in it and to see that the priests build a chapel there. I must also pray, she said, for the conversion of sinners. I asked her many times what she meant by that, but she only smiled. Finally, with outstretched arms and eyes looking up to heaven, she told me she was the Immaculate Conception.
