According to my understanding, ape beej ape khao bachan is matter of doer ship, if you do the actions with doership*/identity/ego then cycle of karma ensues then you will get fruit based on those actions. But if you allow actions spontaneously coming directly from consciousness then its direct expression of that consciousness-vahiguru- everything is expression of divine. Sukhmani sahib talks about this over and over again - how vahiguru is doing everything, enjoying, expressing itself. There is only one and there is no one besides one.
Regarding- Akhan jor gurbani vak- it alludes to the point there is no free will everything is per-odained- you can will what you want but you cannot will what you will which means backdrop of everything is pre-determined*.
Doership*
Ang-278
ਜਬ ਇਹ ਜਾਨੈ ਮੈ ਕਿਛੁ ਕਰਤਾ ॥
जब इह जानै मै किछु करता ॥
Jab ih jānai mai kicẖẖ karṯā.
As long as this mortal thinks that he is the one who does things,
ਤਬ ਲਗੁ ਗਰਭ ਜੋਨਿ ਮਹਿ ਫਿਰਤਾ ॥
तब लगु गरभ जोनि महि फिरता ॥
Ŧab lag garabẖ jon mėh firṯā.
he shall wander in reincarnation through the womb.
*Pre-determined
