Prabhupāda: In the Bhagavad-gītā it is stated that there are three planetary system, upper, lower and middle. So ūrdhvaṁ gacchanti, those who are in the modes of goodness, they are allowed to live in the upper planetary system. And those who are in the modes of passion, they are allowed to live in this middle planetary system, and those who are in the modes of ignorance, they are allowed to live in the lower planetary system.
Reporter: Now where would the moon planet fit?
Prabhupāda: Moon planet is the upper. That is the beginning of upper planetary system. Still upper, upper, upper, there are many layers.
