Turn in the door once and turn once only
Response to Sophie Perkel
Reading the Brihadaranyaka source that connects to this section of the poem, I notice in Chapter five that the descriptions of "truth" and "falsehood" remind me of the third/fourth person from our previous readings. "The gods worship truth (satya), pronounced with three syllables, "sa-ti-yam". Sa and yam represent Truth, ti represents falsehood. "falsehood is surrounded on both sides by truth, and becomes truth." Falsehood being in-between is similar to how the "third person" is in-between, and if falsehood becomes truth by being surrounded by truth, then could the entity that is the third person, what does the "third person" become?
Sophie has an intriguing point here about the "third (or fourth) person." Following her analysis of the three syllables "sa-ti-yam" of satya (truth), where "ti" means falsehood while the other two represent truth, then it would be logical to surmise that Eliot believes a third entity can become truthful if surrounded by truth. I don't necessarily believe that Eliot thinks falsehood can become true, but maybe that falsehood can become normalized and authentic to an individual. For example, if we build on my past annotation where I argued that there are three entities - God, an individual, and a third entity which tempts or distracts the individual from a clear path to Heaven or spirituality. In this case, the true entities that "count" (by the words of "the Thunder" earlier in this section) in life are God and the individual. Thus, that third entity which cannot be defined as it would be different for each entity is the falsehood because it should not be the core of living. Once we understand that, we can apply Sophie's theory and conclude that Eliot believes that although a distraction will never truly live up to the importance of an individual or the deity which they follow, enough prioritization of a sin will make it a habit and a necessity. In this way, that third entity of sin and temptation can become an authentic aspect of someone's life, because they have placed a falsehood on such a pedestal that it has become (to them) as truthful as God.
