Well Ganesha is son of hindu god Shiva.
He was givne a boom that all works will start after his worship by his father.
He has two wifes Ridhi and Sidhi and doughter Santoshi Mata.
in past there are about seven of his incartion(Das does not rember correctly).
There is one sect called Ganpatya which behold Ganesha as god.
in common Ganesha is remover of obstructions.
Swastik is also called Ganesh and gerko roamen God of start or first is called Jenees and First Month of January is named after it.
In Pagan Red Indians and in Shinto there is worship of elephant face god.face was of indian elephant.Shinto ism calls it vinayaka.
But most have know conveted to Christianity etc.
coming to Sikhism is Dasham Granth,Tenth Guru deifis Shivas boom to Ganesha that he must be worshipped first and this is part of origeonal Rahiras Sahib.
i will not pester Ganesha at start.
Never will I rember Krishna or Vishnu.
(My) Ear herd them by no recogation with them.
My heart is with that's feet(refuge).
Mahakal(controller of time or higher then time) is our protector.
Mahaloh(super or stronger then metal) I am your slave.
As no one can be Mahakal or Mahaloh but Akal so that Akal is in all is our Guru.
that Guru is in Ganesha as it is in rat(which is considered as vehcleof Ganesha).
In elephant from from there into ant does Akal exists.
So in any case Ganesha can not be equal to Akal so can not be our Guru.
But it does get its power from our Guru.
