February 6 marks the day of remembrance for Blessed Ksenia of Petersburg.

Ksenia of Petersburg, known in the world as Ksenia Grigoryevna Petrova, was an Orthodox fool-for-Christ from a noble family who lived in St. Petersburg. There are no documentary records of her life, and the first accounts of folk legends about her appeared in the 1840s. According to these legends, she was born in the first half of the 18th century, presumably between 1719 and 1730. Her father's name was Grigory, and her mother's name is unknown. In adulthood, Ksenia married the court singer Andrey Fyodorovich Petrova. They lived in St. Petersburg in a house that was later named after her husband, 'Andrey Petrova Street.' Now, on this site stands the Church of St. Ksenia of Petersburg.

After the unexpected death of her husband, 26-year-old Ksenia chose the path of foolishness, seeking to denounce worldly values. She gave her husband's house to one of her acquaintances, began to wear his clothes, responded only to his name, and claimed that he was alive while Ksenia had died. When her husband's clothes wore out, she started wearing a red blouse and a green skirt or vice versa, and on her bare feet, tattered shoes. She was offered warm clothes and shoes, but she refused.

Ksenia did not accept alms, taking only small coins, which she then distributed to others. She spent her days wandering the streets of Petersburg, sometimes visiting acquaintances, having lunch with them, and conversing. For a long time, it remained a mystery where she spent the night. It was later revealed that she spent her nights in the fields, praying on her knees until dawn and bowing in all directions.

Additionally, at night, Ksenia carried bricks for the construction of the church at Smolensk Cemetery. She predicted the death of Empress Elizabeth Petrovna and Ivan Antonovich. Thanks to her gift of foresight, she helped people in their life affairs and the salvation of their souls. Special prosperity accompanied those to whom she gave anything.
