What is the overall theme of the poem tintern abbey?

In 'Tintern Abbey' Wordsworth sees 'Nature' as a place of permanence - and therefore a shelter and retreat from the stresses and confusions of urban life in the Industrial Age.

Wordsworth usually sees 'Nature' as a place of calm and safety. Coleridge, and later Tennyson, had a much more ambiguous address to it.He sees 'Nature' as guardian, nurse ,teacher and also a source to modify man's behaviour.Wworth considers 'Nature' a great healer as well because its the source of relaxation,peace and solace for man in hours of weariness and distress.
