What is the second stage of wordsworth's growth of mind in the poem "Tintern Abbey" ?

In the second stanza Wordsworth tells his readers that his first visit to this place gave him "sensations sweet" when he was in the "lonely rooms" of the city. He intimates that these "feelings... / Of unremembered pleasure" may have helped him to be a better person, perhaps simply by putting him in a better mood than he would have been in otherwise:

As have no slight or trivial influence

On that best portion of a good man's life,

His little, nameless, unremembered, acts

Of kindness and of love. Nor less, I trust,

To them I may have owed another gift,

Of aspect more sublime; that blessed mood,

In which the burthen of the mystery,

In which the heavy and the weary weight

Of all this unintelligible world,

Is lightened
