What does the speaker in this poem say will happen to "thy thoughts, when thou art gone"?

Music, When Soft Voices Die (To--)
by Percy Bysshe Shelley

Music, when soft voices die,
Vibrates in the memory.--
Odors, when sweet violets sicken,
Live within the sense they quicken.--

Rose leaves, when the rose is dead,
Are heaped for the beloved's bed--
And so thy thoughts, when thou art gone,
Love itself shall slumber on.
