Letter written on 7 Dec 1961 om
This is one of hundreds of letters Osho wrote to Ma Anandmayee, then known as Madan Kunwar Parekh. It was written on 7th December 1961 in the afternoon. 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 "प्रिय मां", Priya Maan, Dear Mom, Beloved Mother. It has a couple of the hand-written marks that have been observed in other letters: a blue number (40) in a circle in the top right corner and a second, pale and mirror-image number (65) in the bottom right corner, but no red tick mark.
We are awaiting a transcription and translation.
