In plain words
In the world, all substances whatever need this atomic energy. This energy is one, not two. This very thing they called in the Veda ‘Ekohaṃ bahuśyāṃ. Ekaṃ sat viprā bahudā vadanti’: that is, though what exists is one only, people have experienced it in many forms and by many names. When the mass of atoms is the main thing for the world itself, the measure of the atoms alone is the main thing for every object in this world too. Here is another small example. This is a wall. When we look at it, this wall appears to us as gross, and as a barrier to what is on the other side. And we think this wall is gross, that it is hard. We believe there is no liquid of any kind in it. This wall too is a mass of atoms. It is made of particles subtler than atoms. To the outer eye, to outer experience, this is a wall. This is everyday experience. But we must try to grasp its true experience as well. When we try to see this very wall with an instrument, the whole wall appears just like a great galaxy of stars. This wall is made of nothing but such tiny particles. In it there are so many gaps of many kinds. The measure between one particle and another takes shape as an atom too.
In the same way, when we examine this world, our everyday experience is one thing and the true experience is another. But the true experience is the basis of this everyday experience. Only by what rests on the true experience, which is the basis, are we able to see the form that rests on it as everyday experience. This is the atomic energy that is the basis of all. This very thing they called aṇoraṇoyān mahato mahīyān. Being an atom, it goes on taking shape as a mighty energy. All the rest of these everyday experiences are changes of form of the true experience. They can be nothing else besides. For the waning or the waxing of the energy of these atoms there is one basic energy that is the root support. That itself is the true experience. The energy of the true experience is one, not two.
Here is a fine example of this. We have set down these numbers: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Of these, apart from one, all the other numbers have no independence of their own.
