Letter written on 15 Oct 1970 (Kusum)
Osho wrote many letters in Hindi to Ma Kusum Bharti and her husband Kapil, then of Ludhiana. Most were addressed to Kusum, but always mentioning Kapil too. 27 were published in Prem Ke Swar (प्रेम के स्वर). Sannyas Wiki has images of all but one of those published in PKS, plus three unpublished ones, plus one in English published in The Gateless Gate.
This letter is dated 15th October 1970. It is one of the few not published in PKS. The letterhead gives Osho's address as CCI Chembers [sic] in Bombay, with his name rendered as Acharya Rajaneesh. The logo is a one-colour version of the Jeevan Jagriti Kendra logo (dark green), but a different colour than the name and address (dark blue). Not many letters were written using this letterhead, as it was soon replaced with a version with "Chambers" and "Rajneesh".

ध्यान जारी रखना।
तेरी संभावनायें बहुत हैं।
लेकिन, तू श्रम ही नहीं कर रही है।
कपिल को प्रेम।
असंग को आशीष।
रजनीश के प्रणाम
