In "The Postmaster," what does" ripping our veins and draining our heart's blood until regaining conciousness" mean?"

These lines come at the end of Tagore's short story.  They
come at a point where Tagore is backed into a corner, of sorts.  He has presented a
narrative that is A) in search of an ending and B) begs to be explained.  Tagore
concludes his discussion of the Postmaster and Ratan with a sense of the unresolved.  In
the case of the former, he recognizes that he broke Ratan's heart, caused her to feel
pain, and for a moment, he experiences these same sensations.  Yet, he rationalizes and
uses his own philosophical background to will this pain away.  Tagore cannot explain why
he does what he does.  Ratan is left to wander the village in search for her
"dadababu."  She wanders in the hopes he returns, and there is an immense portrait of
sadness in this orphan who found belonging, only to be exiled back into the rootless
world again.  Tagore cannot explain why she feels what she feels.  This is where he is
by the end of the story.  Essentially, he is left to philosophically and rationally
explain the unexplainable and irrational domain of emotions.  It is here where Tagore
essentially talks about how consciousness in the world is a crushing combination of
despair and hope. The landscape of the former is punctuated by those moments of the
latter.  Within this configuration, hope, the belief in redemption and the pain that
follows is what "rips our veins" and helps to "Drain our heart's blood until regaining
consciousness."  Yet, while this experience might prevent individuals from believing or
pursuing hope or redemption, it is not the case.  Individuals fall into "snares of
delusion" to pursue these ends again.  Consciousness, for Tagore, is a setting where the
despair and hope dynamic of Ratan wandering, exiled from community, seeks to find
belonging, somewhere, anywhere.  It is in this vision where Tagore offers his own
philosophical explanation that helps to allow better understanding of both the
postmaster and Ratan, and end the short story in a manner where we cannot help but apply
these lessons into our own lives and experiences.
