My take on this is that silence is the language of God when the universe is in Pralaya (rest period) and all manifestation during a MahaManvantara is a communication (energy, intent, cause, effect, etc.) of God.

As HBP stated in 1888 in the Secret Doctrine: "It is the one life, eternal, invisible, yet Omnipresent, without beginning or end, yet periodical in its regular manifestations, between which periods reigns the dark mystery of non-Being; unconscious, yet absolute Consciousness; unrealisable, yet the one self-existing reality; truly, “a chaos to the sense, a Kosmos to the reason.” Its one absolute attribute, which is itself, eternal, ceaseless Motion, is called in esoteric parlance the “Great Breath,”* which is the perpetual motion of the universe, in the sense of limitless, ever-present space. That which is motionless cannot be Divine. But then there is nothing in fact and reality absolutely motionless within the universal soul. "

That Great Breath which is the manifested universe is God's language.
