In poetry, the start of a new stanza often signals an introduction of a new thought or idea.
Stanza is a grouped set of lines within a poem, which is usually set off from other stanzas by a blank line or indentation. Stanzas can have regular rhyme and metrical schemes. Poets usually start a new stanza when they are transitioning from one thought to another one in their poems. There are many unique forms of stanzas.
