Hayagrīva: Like I mentioned, there are three planets, three... There are the lower planetary systems, middle planetary systems, and higher planetary systems. And this earth is considered to be in the middle planetary system of the universe. It's called a middle planet.
Reporter: Would that relate to anything that we're talking about?
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.
