Prabhupada, Surat, December 17, 1970: […] There is a planet which is called Siddhaloka within this universe. In the Siddhaloka they have got full perfection of life. And sometimes the yogis can demonstrate. In the Siddhaloka, for going from one planet to another planet there is no need of vehicles, no need of aeroplane. They can fly themselves in the sky.
Sometimes we have seen pictures — a beautiful man and woman with wings. That is, of course, imagination. Maybe. We have not seen the inhabitants of the Siddhaloka, but we find it from Vedic scriptures that they can fly in the sky without any help of aeroplane or similar machine. They travel from one planet to another by yoga-siddhi. As the yogis can transfer themselves from one place to another without any difficulty, similarly, the inhabitants of Siddhaloka, they can fly in the sky.
Yamuna: In Siddhaloka there are angels? That means angels?
Prabhupada: Yes. [break] There are many different types of human beings. So, the Caranas, the demigods, the Siddhas. Don’t think that in every planet you can find out the same bodily features. There are different bodily features. So in Siddhaloka they have got the same bodily features, but their powers are far, far greater than ours.
