As time went by, her desire for the Blessed Sacrament grew. She thought that if she joined the convent, she would get to receive communion sooner. She joined a cloistered Dominican community at age nine. (It was unusual at the time for a girl her age to enter the convent.) However, she was still denied the opportunity to receive Holy Communion.
Miraculously, a consecrated Host, which was reserved in the tabernacle, left the tabernacle and hovered over her head. She was in a state of ecstasy. After a long time, her superior noticed she was not going about her duties around the monastery and went looking for her. She discovered Imelda just where she left her, in the chapel; but she was in a state of rapture as the miraculous Host continued to be elevated above her head. The superior ran to get the priest, who promptly came. He got a paten and held it under the Host. The Host dropped onto the paten, and the priest gave Imelda her First Holy Communion. Imelda knelt in her spot in the chapel to pray in thanksgiving, and her Dominican sisters joined her for a time. Eventually, they left her alone to contemplate this great gift.
Later that day, her superior again became concerned and looked for her only to discover that after several hours, little Imelda was still in the chapel. The superior wanted to make sure she got some rest and approached with the intention of asking her to retire. However, Imelda had died, kneeling serenely and in prayer. It is said she died for joy and love of the Holy Eucharist. Miracles were immediately attributed to her intercession, especially the restoration of sight to one man from her town who had been blind. Her body remains incorrupt to this day.
