Dylan Thomas began to write poetry with the assumption that we start to die from the moment we are burn, even from the moment we are conceived in the mother`s womb. This continual process of conceiving, living and dying links us with everything else in the world. The death of a flower is felt as the poet`s own death under the same force, because the forces of destruction work through all things at the same time. This is the whole burden of his best-known poem, `The force that through the green fuse drives the flower`, and continues throughout his poetic career. To Thomas, the poet`s consciousness, his body, and the world around him are one. And the language which expresses this interpenetration and totality calls attention to itself as language. He tries to create structures of words that can be understood only by a single leap which carries the reader into meaning. Sometimes the meaning of his poem grows slowly as something which enters through the powerful impression of sound and feeling the poem makes even when it is not understood. The poems that express the merging and the interpenetration of consciousness, body, and cosmos are peculiar in their breeding and making of images. The poet lets an image be made in him. It is not a matter of volition or reasoning. The center is "a host of images", that is, at once the possibility of a vast number of images and the negation of each one. It both contains and denies all the images which may come from it. In such processes the poet struggles to bring the "overclothed blindness" into the "naked vision", to come "from darkness towards some measure of light", and approaches "that momentary peace" in such poems as `Fern Hill` and `Poem in October`. Such qualities of Thomas` poetry derives from the tradition of Welsh bardic poetry. To this tradition may be attributed his confidence in the romantic and apocalyptic manner. So the Welsh bardic tradition that had been melted into his blood from his childhood through the protestant religious festival might naturally have fostered the sensibility that is both primitive and religious in the modern world.
