My dear son Nārada, know from me that there are seven lower planetary systems out of the total fourteen. The first planetary system, known as Atala, is situated on the waist; the second, Vitala, is situated on the thighs; the third, Sutala, on the knees; the fourth, Talātala, on the shanks; the fifth, Mahātala, on the ankles; the sixth, Rasātala, on the upper portion of the feet; and the seventh, Pātāla, on the soles of the feet. Thus the virāṭ form of the Lord is full of all planetary systems. (Srimad Bhagavatam 2:5:40-41)
The universe is divided into fourteen planetary systems. Seven planetary systems, called Bhūr, Bhuvar, Svar, Mahar, Janas, Tapas and Satya, are upward planetary systems, one above the other. There are also seven planetary systems downward, known as Atala, Vitala, Sutala, Talātala, Mahātala, Rasātala and Pātāla, gradually, one below the other.
Pitr are souls of those who are deceased from the family. Where is Pitra loka situated?
How are Pitr related to Pitr loka? When do they come here? For how much time do they stay in Pitr loka?
