"Flashback vs. present" variation

He walks on my left side -
where my heart is,
where my past is,
where my weak side is,
where my pain is,
where my death was.

He walks on my left side -
he holds my heart,
he is my present,
he supports me,
he cures,
he awakes me.

He is transmitter, I am receiver, life is neverending cycle.
