Hz Raja sahib loved Mawlana and his Masnavi very much. Although he had read the Masnavi from cover to cover at least 17 times he would become overjoyed when someone else quoted a verse to him. Most of the discussion in his majalis was based on the Masnavi and often he would comment upon a single verse for days. If anyone expressed the desire to read the Masnavi he would buy the book for him from his own pocket; and through his baraka even labourers who could hardly read and write were not only able to read the text in Persian but also memorise it’s verses.
The Masnavi is a masterpiece of Sufi literature and has been taught by Sufi masters to their students for centuries. In it Mawlana has presented “the root of the root of the root of religion”.
Ibrahim Gamard has a wonderful website on the Masnavi where he has corrected some of the flagrant mistakes made by contemporary “translators” of Mawlana. I’ve added a permanent link to it under Sufism.
