"For God is silence, and in silence is he sung by means of that psalmody which is worthy of Him. I am not speaking of the silence of the tongue, for if someone merely keeps his tongue silent, without knowing how to sing in mind and spirit, then he is simply unoccupied and becomes filled with evil thoughts: he is just keeping an exterior silence and he does not know how to sing in an interior way, seeing that the tongue of his ‘hidden man’ has not yet learnt to stretch itself out even to babble. You should look on the spiritual infant that is within you in the same way as you do on an ordinary child or infant: just as the tongue placed in an infant’s mouth is still because it does not yet know speech or the right movements for speaking, so it is with that interior tongue of the mind; it will be still from all speech and from all thought: it will simply be placed there, ready to learn the first babblings of spiritual utterance."
