Ultimately, our Earth too falls within the realm of Dharam Khand because the whole creation is within the 5 Khands and the word Dharamshala is for both this Dharti (Earth) because this is the Shaala of Dharam and Karam, and for the Dharti of Dharam Rai as the name implies. The exit to the higher Khands is through Dharam Khand and till one is released from Dharam Khand, one keeps going to heaven, hell and then taking birth in many Karam Bhoomis like our Earth.
