Based on the concerns posted in the last post, I have done another modification to the list:
1. Use Hujwiri's Kashf al-Mahjub to replace Ahmad Sirhindi's Letters - the earlier work is much more representative of the whole Indian Sufi tradition than Sirhindi.

Bengali wasn't included (since it flourished in late 19th / early 20th century); and for balance if Marathi is included through Tukaram, then we risk overrepresenting language from Maharashtra (since Sattasai is Pakrit from that area).
