Raising my eyes to the chapel, I saw standing on the altar, tall, vibrant, majestic, full of beauty and mercy, the Blessed Virgin Mary as she is represented on the Miraculous Medal of the Immaculate Conception.At this sight I fell on my knees on the spot where I had been standing; several times I tried to raise my eyes to the Blessed Virgin, but her radiance and my feeling of respect made me lower them; this did not prevent me, however, from being very aware of the apparition.
