i dont understand the poem"a light exists in spring" by emily dickinson. can someone plz help me analze this poem.thank you

It looks like it's talking about spring, but that is just hidding the other subject wich I think it's youth and how fast it desapears in your life. The light in the poem, is youth that fades away slowly, and then yet so rapidly. It is the part of ones life wich is more tresured when it's gone.

The light could also represent life as in oposition to death wich would be represented by the shadow, and the spring would be the time of youth in ones life.
