The great sage Sukadeva Gosvami answered: All the hellish planes are situated in the intermediate space between the three worlds and the Garbhodaka Ocean. They lie on the southern side of the universe, beneath Bhu-mandala, and slightly above the water of the Garbhodaka Ocean. Pitrloka is also located in this region between the Garbhodaka Ocean and the lower planeary systems. All the residents of Pitrloka, headed by Agnisvatta, meditate in great samadhi on the Supreme Personality of Godhead and always wish their families well.
