Born Helena Kowalska (1905-1938), a Polish mystic and apostle of Divine Mercy. Having entered the Carmelite convent in Krakow, she lived intense mystical experiences with angels.
"Suddenly an inconceivable fire of love gushed forth from my soul toward the Creator. Unable to bear the longing that rose from my soul toward Him, I prostrated myself, humbling myself in the dust.
I praised Him for all His creatures, and when my heart no longer had the strength to bear what He felt, I burst into sobs. Then my guardian angel touched me and said: 'The Lord sends me to tell you to get up.'
I obeyed immediately, but I did not feel consoled; rather, the longing for God invaded me even more."
One day during adoration
"One day, while I was in adoration, my soul suffered atrociously and I could not hold back my tears; then I saw a spirit of incredible beauty who told me: 'The Lord orders you not to cry.'
After a moment I asked: 'Who are you?' And he replied: 'I am one of the seven spirits who stand night and day before the throne of God and praise Him constantly.'
However, that spirit had not extinguished my longing for God; on the contrary, it had increased it. The beauty of the spirit derives from his close union with God.
He does not leave me for a single instant, he accompanies me everywhere. The next day during Mass, before the elevation, he began to sing these words: 'Holy, Holy, Holy', and his hymn, impossible to describe, resonated like the voices of thousands of people."
The Guardian Angel at the convent door
"When I understood how dangerous it is in this period to be near the entrance door, due to revolutionary unrest, and how many wicked people hate convents, I asked God for help and prayed Him to ensure that no ill-intentioned person would dare approach the door.
Then I heard these words: 'My daughter, from the very first moment you were entrusted with this task, I have placed a cherub on guard. Therefore, you must have no fear.'
After returning from my meeting with the Lord, I saw a slight white cloud enveloping a cherub with clasped hands, whose gaze was like lightning."
The Seraphim gives the host to Saint Faustina near death
"A great light surrounded the Seraphim: the divinity and divine love were reflected in him. He wore a golden garment, covered with a surplice and a transparent stole.
The chalice was made of crystal, covered by a veil that was also transparent. As soon as he gave me the Lord, he vanished. Once, a certain doubt arose in me a little before communion, and the Seraphim, accompanied by Jesus, suddenly appeared before me.
I prayed to Jesus and, having received no answer, I asked the Seraphim: 'Could you not hear my confession?'.
And he replied: 'No spirit in heaven has such power.' At that moment, a host rested on my lips."
