I am speaking material because every living entity is spiritual spark. He is covered by this material body. Just like you are covered by your shirt, coat or gown, dress, similarly we are living entities, we are all spirit soul, part and parcel of God. God is the Supreme Spirit, and what in your Christian language it is called Holy Ghost, so we call ātma, or the Supreme Spirit.
So we are all part and parcel of the Supreme, just like the sparks of fire. Fire we have got experience, and naturally there are some sparks also. So you cannot avoid the sparks. Similarly, the Supreme God is just like fire, and we are just like sparks. So qualitatively the big fire and the spark fire, both of them are fire. The spark fire, if it falls on your cloth, it will immediately burn and make a black spot, and the part where it is, it will burn.
So the burning power is there, either in the spark or in the big fire. But the big fire can, I mean to say—what is called—burn many things, and the small spark fire, they cannot burn very large quantity. But the burning power is there. Similarly, the . . . just like creative force. God has got the creative force; you have got also the creative force. But your creative force is very small, minute. Just like God has created this cosmic manifestation. There are innumerable, numberless planets are floating in the air.
You have also created something, Sputnik, that is also floating in the air. We are very much proud, scientific achievement, that you have discovered or manufactured the Sputnik, running so high. But in comparison to this planetary system—millions of planets are floating in the air—what is this sputnik? It is nothing, although we may be very proud, "Oh, we have discovered this Sputnik."
But according to Vedic literature, we find that the living entity, of which the human being is considered the first class, they have got also the intelligence to manufacture or create something which can fly in the air. And we are in this planet, and in other planets there are living creatures. Just like there is a planet which is called, in Sanskrit language, Siddhaloka.
Siddhaloka. In that planet the residents they can fly without any sputnik or aeroplane. As we are trying to go from one place to another by aeroplanes, they can travel from one planet to another without any machine. By mantra-yoga they can fly. These informations are there.
In other planets there are very many intelligent persons. They are called demigods, because they are very, very intelligent. Their duration of life is very long. Just like in the moon planet. In moon planet the duration of life—I am speaking from the Vedic literature—is ten thousands of years. And what is that ten thousands of years? In our calculation, six months make one month for them.
