AAD ji..
Gurfateh.
You have arrived at the correct conclusion.
GURU NANAK JI SAHIB set ALL the Parametres of GURMATT.
ANY and ALL...whatever we have in Sikhi/Gurmatt TODAY..has its beginning in our FOUNDER.

The successor Nanaks...elaborated..grew...contributed/added...to the CORE that Guru nanak ji had already set in place.
1. The EK-OANGKAAR Concept that sets apart Guru nanak ji from all others..
2. Talk..discuss..debate.. Travel TOWARDS....others...not "demand" they come to you !! Talk their Language..not demand they learn yours.....ask questions, provide answers..ENGAGE !!!
3. Stand up to tyranny..injustice...stand on TRUTH and TRUTH alone...regardless of the consequences
4. Be prepared...to sacrifice...suffer...
5. The DHARAMSAAL..in EACH and EVERY HOUSE...( Today the Sri Guru Granth Sahib Ji must be in each and every House to provide Spiritual GUIDANCE/SUPPORT ) Ghar Gar ander Dharamsaal...
6. The REHIT.....Naam japp Kirt Kar waand chhak...the Morning Jap, Evening Rehrass and night sohila
7. The Guru ka Langgar...SANGAT..PANGAT....Shabad ka langgar for MIND..Food for body...
8. POTHI to write down Gurbani, collected Banis of Bhagats on travels...percursor of AAD Granth/and Mark of Gurgadee (tilak) is passing down of thsi Pothis of Gurbani...
ALL THESE and many more of the CORE INSTITUTIONS of Gurmatt come from Guru nanak ji...the MASTER PLANNER>>ARCHITECT>>and all.....
Bhai Gurdass Ji who RECORDED all these...is evidence par excellence.
