Today, she is best known for her transcription of a series of extraordinary spiritual instructions, of which she was one of the recipients in Hungary during World War II.

Soon Gitta Mallasz resumed working in graphic art and joined Hanna Dallos in the atelier which she ran with her husband Joseph Kreutzer.

Once antisemitism gained political power in Budapest, the aristocratic Gitta Mallasz took over the commercial management of the atelier from Hanna and Joseph, who were Jewish just like Lili Strausz.

Hanna and Joseph rented a small house in the outskirts of Budapest and reduced their activities to the absolute essentials.

[2] The 25 June 1943, was the beginning of Talking with Angels,[3] seventeen months of spiritual instructions received and transmitted by Hanna, which ended up in an old college building transformed into a workshop for manufacturing military uniforms.

[5] They never returned; Gitta Mallasz found herself alone in possession of a few black covered notebooks containing the transcripts of the instructions.

Eventually, the writer Claude Mettra, producer at the French public radio station France Culture interviewed Gitta Mallasz about her spiritual adventure in his weekly program on March 22, 1976.

[9] From then on Gitta Mallasz dedicated the rest of her life to commenting on Talking with Angels, and guarding against false interpretations be it in conferences or in books.

She gave up her little house in Périgord and moved to live in Tartaras (Ampuis) in the vineyard region of the Côte-Rôtie in the vicinity of her close friends Bernard and Patricia Montaud.

[13] Gitta Mallasz was recognized Righteous among the Nations in June 2011 for having saved a hundred Jewish women and children in Budapest in 1944.
