Letter written on 10 Oct 1961
This is one of hundreds of letters Osho wrote to Ma Anandmayee, then known as Madan Kunwar Parekh. It was written on 10th 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 (25) in a circle in the top right corner, a red tick mark, and a second number (51) in the bottom right corner.
