Unexplained fragrance of roses at the tomb of St. Therese

St. Therese of Lisieux promised to spend her heaven doing good on earth and to let fall a shower of roses. I always thought this was poetic language, not literal. During my pilgrimage to Lisieux in 2022, I was kneeling at her reliquary, praying about a difficult decision in my life. Should I leave my career in London to enter seminary? I had been agonizing over this for months. Suddenly, the most intense fragrance of roses filled the air around me. There were no flowers in the chapel. No one near me was wearing perfume. I looked around, confused. The woman kneeling next to me, a stranger, turned and said in French, "Do you smell the roses?" She was crying. I took it as my answer. I applied to seminary the following month. I am now in my second year of formation, and I have never been more at peace. The fragrance lasted about five minutes and then faded. But the certainty it gave me has not faded at all.
