Letter written on 6 Oct 1961
This is one of hundreds of letters Osho wrote to Ma Anandmayee, then known as Madan Kunwar Parekh. It was written on 6th October 1961. The letterhead has a simple "रजनीश" (Rajneesh) in the top left area, in a heavy but florid font, and "115, Napier Town, Jabalpur (M.P.) in the top right, in a lighter but still somewhat florid font.
Osho's salutation in this letter is a simple "मां", Maan, Mom or Mother. It has a few of the hand-written marks that have been observed in other letters: a blue number (24) in a circle in the top right corner, a red tick mark, and a second number (50) in the bottom right corner.
We are awaiting a transcription and translation.
