Mokham Singh is spot on. Sikhi says a person gets what they are working for.
There are 5 realms, Dharam Khand, Gayan Khand, Saram Khand, Karam Khand, and Sachkhand.
Dharam Gyan and Saram Khand are all subjected to Mahakali. So when the great destruction comes all these are absorbed back into the creator, and souls have to play this game again. Karam Khand and Sach Khand are not part of the creation, and in Sikhi this is seen as true mukti.
Also watch Maskeen Ji Katha on Khands. He has many.
