Discuss the philosophy of life as expressed by Rabindranath Tagore in the post master?

Key here is the fact that the Postmaster is sent to the village of Ulapur as a colonial agent of the British, so that this little industry town can have a functioning post office. The Postmaster is, in turn, an agent of the British economic and colonial projects in India. Naturally they would select an educated man, but the price of the Postmaster putting that education to good use is finding working conditions that alienate him. Such alienation was a common condition of people involved with industry in the late 1800s (the time this story was written), and was a trope explored by writers ranging from Charles Dickens to Karl Marx.

At the end of the story, we get a contrast between the educated Postmaster’s “philosophy” and Ratan’s uneducated naivete. These are cast as equal burdens, with the Postmaster’s flippant decision to leave Ratan behind because life is full of separations and deaths portrayed as comparably tragic to Ratan’s delusional hope that Ratan might one day return to the village for her. It’s a mysterious little parable that doesn’t have a clear moral, but rather offers a meditation on a fundamental human tragedy that undergirds both loneliness and desire.
