Maharloka, also called Muni-loka, is the fourth-highest planet of the material universe. It is the abode of the great sages and saints like Markandeya. Below it is Swarga-loka and 20,000 yojans above it is Janaloka.
The residents of Maharloka are all great sages and saints. They can move between lokas in the material universe at an unbelievable speed. They are always engrossed in the devotion of God and are all really knowledgable. Their life span is a day of Brahma. When the mahapralaya comes, they either exit the material universe and enter Vaikhunta and reside there eternally or die in the mahapralaya.
