The secret of the whole of creation can be traced to the understanding of what is meant by capacity. Capacity is, so to speak, the egg of creation; all of this manifestation which is known to us, as well as that which is unknown to us, is formed in some capacity. The sky is a capacity. Capacity is that which makes a hollow in which the action of the all-pervading existence may produce a substance. All the stars and planets which we have discovered and those which are not yet discovered, what are they? They are all capacities. And what do they contain? They contain, each one according to its capacity, whatever that capacity is able to preserve within it and give birth to; that is why one planet is not like another planet nor one star like another star.
