The Ahiyapur Pothi is said to be one of the Govindwal pothi that is said to have been used to compile the original Bir of Siri Guru Granth Sahib jee. Siri Guru jee definitely used Govindwal pothis to compile the Aad Bir of Siri Guru Granth Sahib jee but what is not clear is whether the Ahiyapur Pothi is one of the Govindwal pothis. It seems most likely that all of the Govindwal pothis are in no longer in existence. Guru Sahib knows the truth.
