In the Zend Avesta, one of the oldest books that we know of, it is said the earth has grown three times in size. Thus spoke Zarathustra.

Interesting thing about Zoroastrianism, which is a religion / way whose book is the Zend Avesta... You can't join. You can't marry into it, you can't convert. You either are or you aren't. I like that. In the book, dogs are held in the highest esteem and the earth is happiest when the bones are dug up, as neither dogs nor humans belong to earth. Interesting to consider, in any event.

BTW Freddie Mercury was Zoroastrian.
