The celebration of Basant Panchami at the dargah is drenched in the yellow of mustard flowers. Songs in the Purabi dialect and qawwalis can be traced to a certain event in the lives of Nizamuddin Auliya, and his equally famous disciple, Amir Khusrau. When the sone of Auliya's sister, Taqiuddin Nuh, died an early death, the Sufi was gripped with pain and remorse that had no end. For days on end, he would remain sorrowful, quiet and morbid. Seeing the condition of his revered spiritual master, Khusrau was troubled and wanted to placate his pains. Khusrau found his opportunity that came in the form of Basant Panchami, the first day of a forty-day spring that culminates in Holi.
