This is clear from the meaning of growing', used in reference to truths that have multiplied through molestations caused by evils and falsities, as becoming strong, for no other truths remain than those which become strong, and therefore as more and more truths become strong, so they grow. The fact that truths are made strong by means of molestations, see immediately above in 6663.
