Dan,

Thank you so much for your feedback.  I really do appreciate it.  As an initial disclaimer, however, I would like to note that the annotation of "Hope you dig", etc.  was not written by me. Rather, it was written by the person who posted the poem for me, apparently out of his enthusiasm for it, but heretofore unbeknownst to me.  I was a little aghast because it seems entirely antithetical to the spirit of the poem, and I would argue to the spirit of all of my poems.  I just thought that I ought to mention this. 

As for your question, the imagery for that line stemmed from the notion of all of today's memories and feelings travelling with us, tucked somewhere within us, though we may not be able to access them at a point.  They are formative and they are alive, even in the process of us aging and dying.  And we carry all of us yesterday's secrets, as well.  Sometimes, we can reach within and extract them and just as often, it seems, they remain hidden.  I often wonder, and struggle with, how our sons or daughters will reflect on our relative amnesis, or hiddenness, when we are rather elderly or have passed away.  The poem is something of a prayer, I suppose, that we all never lose the essence of what we've had in living.
