One who knows
the unmanifest brahman
and at the same time the manifest brahman,
having overcome death
by the worship of the manifest brahman,
attains to immortality
by the worship of the unmanifest brahman.
We cannot draw a circle without a center. The circumference is drawn all around the center. As the circumference moves away from the center it grows larger and larger. If we mark two points on the circumference there will be some distance between them, and if we draw two lines from the points on the circumference joining the center, the distance between the lines will go on decreasing as they approach the center. The distance between the lines will disappear as soon as they reach the center. There may be any amount of distance between two lines on the circumference, but as these lines approach the center, they go on coming closer to each other, and having reached the center the distance disappears altogether. At the center they are one. If we continue to draw these lines beyond the circumference, the distance between them will go on increasing as the circumference increases.
Through giving this geometrical illustration, I wish to tell you two or three things to explain this sutra. The first point is this; the element which is called the unmanifest brahman is the central brahman. The whole expanse of the existence comes out of it: and life – the circumference – goes on spreading out and out from this center.
After deep inquiry during the last few years, science has arrived at a new theory – that of the expanding universe. It was always believed that the universe is what it is, nothing added, nothing subtracted. But modern science says the universe is not simply that which now is, but it goes on expanding every day, just as a balloon goes on expanding if someone pumps air into it. Such is the expanse of this universe. But it is not the same as it was yesterday. It expands by millions of miles during every twenty-four hours. Continuously it is expanding. The stars we see at night are traveling far away from one another every moment.
This is interesting: there must have been a moment when this universe was so contracted within itself that it must have been at the zero center. As you go back and back in time, the universe is found to be smaller and smaller, becoming more and more contracted. There must necessarily come a moment when this whole universe was contracted into its very center. Then its expansion began, and that process has been going on ever since. The circumference is getting larger and larger every day. Scientists say we are unable to forecast how long it will continue to expand. This is an endless expansion. It will go on growing larger and larger.
