OD is an abbreviation for the Latin term oculus dexter which means right eye. Notice that the right eye information is asked for first even though we typically read from left to right.
OS is an abbreviation of the Latin oculus sinister which means left eye. That will be referenced on the far right column of the prescription.
SPH is short for sphere. The sphere of your prescription indicates the power on the lenses that is needed to see clearly. A plus (+) symbol indicates the eyeglass wearer is farsighted. A minus (-) symbol indicates that the eyeglass wearer is nearsighted.
CYL is short for cylinder. The cylinder indicates the lens power necessary to correct astigmatism. If the column has no value (is blank), it indicates that the eyeglass wearer does not have astigmatism. If this is the case on your prescription, you can leave it blank when entering it in.
AXIS is a prescription will include an axis value for those with astigmatism. This number represents the angle of the lens that shouldn't feature a cylinder power to help correct your astigmatism.
ADD is short for "additional correction." This is where details about bifocals, multifocal lenses or progressive lenses would appear.
In contemporary times, as Manipuri society faces rapid changes—political uncertainties, environmental shifts, and cultural erosion—the endless tale gains new relevance. It becomes a metaphor for resilience. No matter how many times the protagonist falls, the story begins again. No matter how many threats appear (the tiger below, the snake above), the act of telling continues. This persistence is a quiet form of resistance: the story survives because it refuses to conclude on a note of defeat.
Second, the never-ending tale serves as a . By refusing to provide an ending, the story mirrors life itself. Human existence is filled with unresolved threads, unfulfilled desires, and open questions. The Etei na thu naba wari humbly admits that some conflicts have no neat resolution. It prepares the mind to accept ambiguity—a vital lesson in a world of complex moral choices.
The Etei na thu naba wari typically follows a repetitive, cyclical pattern. A protagonist—often a clever trickster, a naive villager, or a wandering sage—encounters a situation that demands resolution. However, each time a solution appears, the narrative loops back to its starting point, or ends with a question rather than a closure. For example, a classic version involves a man who climbs a fruit tree. As he reaches for the last fruit, the branch breaks, but he catches a vine. As he swings, he sees a tiger below and a snake above. A listener asks, “What happened next?” The storyteller shrugs and begins again: “There was a man who climbed a fruit tree…” The story never concludes. etei na thu naba wari
In the rich tapestry of Meitei oral literature, stories are not merely pastimes; they are vessels of dharma, social codes, and metaphysical truths. Among the countless narratives passed down through generations in the valleys of Manipur, there exists a peculiar genre or a recurring motif known as Etei na thu naba wari — the story that has no ending. At first glance, such a tale might seem frustrating or incomplete. Yet, upon deeper reflection, this “endless” narrative structure holds profound philosophical and pedagogical significance.
Why would a culture cherish such a frustrating form? The answer lies in the educational function of the Etei na thu naba wari . In contemporary times, as Manipuri society faces rapid
Third, these tales act as . Because the story is circular, it can be told for hours, even days, with each storyteller adding a new twist or returning to the core loop. The audience participates by shouting “Etei na!” (“It is still the same!”) or by offering their own impossible solutions. This turns storytelling into a ritual, strengthening communal bonds. The story never ends because the community never stops telling it.
First, these stories teach . In an age of instant gratification, an endless story forces the audience to abandon the need for a climax. Instead, they focus on the process—the rhythm of language, the minute variations in each repetition, and the shared experience of anticipation. Children listening to such tales learn that not every journey has a destination; sometimes, the journey itself is the meaning. No matter how many threats appear (the tiger
Moreover, the Etei na thu naba wari challenges the very definition of a “story.” Western narratives, heavily influenced by Aristotelian poetics, demand a beginning, middle, and end. But Meitei wisdom recognizes that some truths are circular. The cycle of birth, death, and rebirth (samsara) has no ultimate ending. The seasons rotate without finality. The Etei na thu naba wari becomes a linguistic echo of this cosmic truth.
