Pressured by her father to marry, she left her family home secretly and went to the larger city of Mlawa. In 1886, she entered an underground religious Congregation known as the Servants of Jesus, since at that time religious orders in her region were under Russian suppression. Founded in Warsaw by Blessed Honorat Kozminski, OFM, Cap, the religious Congregation’s apostolic mission was to work especially among servants. In 1893, when Father Joseph Sebastian Pelczar needed Sisters to work with servants in Krakow, the superiors of the Servants of Jesus sent Ludwika, who was known to always fulfill her obligations with great zeal and love.  Always open to the needs of others and the inspiration of the Holy Spirit, Ludwika shared the concerns of St. Joseph Sebastian Pelczar about the lot of the servants, the poor and the sick.  From this charitable-apostolic initiative, came the new religious Congregation of the Sister Servants of the Most Sacred Heart of Jesus, of which Mother Klara became the co-Foundress, first member and superior. God’s inspiration to her as well as the directives she received from the Founder of the
Congregation, Father and later Bishop Joseph Sebastian Pelczar of Przemysl, found permanent expression in the spirituality and apostolic mission of the Sacred Heart Sisters. Mother Klara died on February 7, 1916 at the Sisters’motherhouse in Krakow, Poland.  The Servant of God was a visible sign of Divine Love. Her personal motto and program of life were the words, “All for the Heart of Jesus.”  The cause of her Beatification has been introduced in Rome, and we pray for her speedy elevation to the glory of the altars.
