is there actually anything called as the devils diary ?? a diary by Lord Lucifer ?

I WANTED TO COMMIT MYSELF TO THE LORD ON THE MOST AUSPICIOUS DAY.. OCTOBER 31...I M TRYING DESPERATELY TO GET BLACK CANDLES BUT AM JUST NOT GETTING IT..WHAT SHOULD I DO...?

Does the movie "The Exorcism of Emily Rose" depict the truth of what really happened ?
