Waheguru Ji ka Khalsa Waheguru ji ki fateh.
The Panj Granthi pothi has the following Banis:
Japji Sahib, Shabad hazareh, Rehras, Sohila, Dakhnee Onkar, Sidh Ghost, Anand Sahib, Bavan Akhree, Sukhmani Sahib nad Asa Di Waar.
There are no arths etc - just the above banis in a small handy sized pothi so it is easier for a young student of Paath to read from and study.
I dont have a dass granthi Pothi with me at the moment,but off hand it also contains the Banis of Guru Gobind Singh Ji - Jaap Sahib, Akal ustat, Swaiyahs, bachittar Natak and a few other banis.
IMHO the Word PUNJ may be used to refer to PUNJVAAN NANAK - Guru Arjun Ji and all banis are from
Guru Granth Ji...and the Dass Granthi - then refers to Daswaan nanak - Guur Gobind Singh ji as all the bansi in this pothi are NOT from
Guru Granth ji...but from Dasam granth.
The 22 Varaan is self explanatory - it contains all the 22 Vaars from
Guru Granth Ji - again in a handy sized pothi for easier handling by students.
The Bhagat bani Pothi contains ALL the Bhagat bani from Guur Granth Ji and includes the Slok Sahiskirti - the difficult sanskrti sloks at Panna 1340++ of SGGS.
i hope this helps.
