St. Margaret Mary spent several years in her childhood with Urbanist Poor Clares who took in young girls to give them an education. This was a normal arrangement at that time.
While at the Poor Clare monastery at Charolles, France, young Margaret made her First Communion at the then-relatively young age of eight-and-a-half years old. She wrote:
“After my First communion, our Lord spread such bitterness over all my little enjoyments that I could find relish in none, though I sought them eagerly. But as soon  as I thought to take part in them with my companions, I always felt something which called me aside... [In the Chapel, before the Blessed Sacrament] I felt that I was in a place of dearest delights.”
Saint Gertrude of Helfta,  a Cistercian nun wrote:
“I understand that, each time we contemplate with desire and devotion the Host in which Jesus is hidden, we increase our love here on earth.”
