Our being is silent, but our existence is noisy. Yet when our noisy actions stop, there is a ground of silence always there. Contemplatives must be in contact with that ground and communicate from that level to keep silence alive for other people.
For the blessed souls who have entered the profound union of divine life: rest and activity, contemplation and action, silence and speaking, receiving the gift of God in love and returning love by waves of thanksgiving and praise, are the same thing.
