In Pureland tradition there is an emphasis on receiving. We receive the grace of Amida. We do not have to do anything in order to receive this other than mentally turn toward the Buddha, which means to take refuge. Although this may be done by a verbal utterance which we call nembutsu, nembutsu can also be silent. Times of silence and solitude can be a wonderful blessing. They can be times when the spiritual forces in one's life rebalance themselves.
There is also an implicit emphasis in PL on the functioning of the unconscious. While much popular spirituality emphasises conscious and deliberate awareness and attention, the Buddhist sense of the mind is really much wider and deeper than this. In fact, any conscious act of the will or consciousness has to involve the ego and so casts a shadow. It must set up an equal and opposite reaction somewhere in the heart-mind. Healthy balance, therefore, requires times when these unconscious compensations can readjust.
In silence we arrive at a receptive place. We cannot control Amida or make the Buddhas bestow their merit but they are always happily doing so anyway. When we become quiet, "With our house all stilled" as John of the Cross says, then we become like a still pool in which the light of the moon can be fully reflected. There is no hamlet in the land into which such light does not shine, but much of the time we are so busy and disturbed that upon the surface of our life the reflection is all broken up. Silence enables us to appreciate the full beauty.
To modify Keats slightly, spiritual truth is beauty and spiritual beauty is truth - that is all you know on earth and all you need to know. The beauty that shines upon us is glorious and satisfying and even the tiniest pool can be a perfect mirror thereof.
