Sachedina #140
Cross-Examination by Mr Jiwa.
Q. Must abide by, yes. And would you also agree with me that the jamat is also asked to obey and follow what's preached in the Ginans, g-i-n-a-n-s, so long as they are not contradicted by a current Imam?
A. Ginans are devotional poetry, and thus as poetry, it is not in a way incumbent for anybody to follow the ginans in the way that you describe. Ginans are, as I say, devotional poetry.

Cross-Examination by Mr Tajdin.
Q. Okay. But you agreed that the Usul-e-deen farman, which is very well known in the community, says that farmans and ginans are the same?
A. As I said to you, this was by the past Imam, the 48th Imam.
Q. Is it valid or not?
A. As I said to you, my interpretation, and it is my personal interpretation, that I follow the guidance given by the present Imam always.
