Letter written on 13 Nov 1961
This is one of hundreds of letters Osho wrote to Ma Anandmayee, then known as Madan Kunwar Parekh. It was written on 13th November 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 just plain "मां" (Maan, Mother or Mom). It has a few of the hand-written marks that have been observed in other letters: a blue number (33) in a circle in the top right corner, a red tick mark, and a second number, assumed to be 59 in the bottom left corner of the back side, which is not seen directly but showing through mirror-image from the back side among the writing on the front. All the letter, somewhat long, is on just the one side, with a PS squeezed sideways on the left side of the page.
We are awaiting a transcription and translation.
