काठमाडौँमा भएको विगत दुई दिनको आन्दोलनले देशलाई गम्भीर संकटतर्फ धकेलेको संकेत देखिएको छ। आन्दोलनका क्रममा २४ जनाले ज्यान गुमाएका छन् भने खरबौँ मूल्यबराबरको निजी तथा सार्वजनिक सम्पत्ति नष्ट भएको अनुमान गरिएको छ।

विगतका जनआन्दोलन, मधेश आन्दोलन, सरकार–माओवादी युद्ध वा २०७२ सालको विनाशकारी भूकम्पजस्ता घटनाको अनुभवले पनि यस्तो प्रकृतिको अराजकता देखाएको थिएन। तर पछिल्ला घटनाले नेपालको राजनीतिक स्थायित्व मात्र होइन, सामाजिक एकता र अर्थतन्त्र समेत गहिरो संकटमा पर्ने आशंका बढाएको छ।

भौतिक सम्पत्तिको ठूलो क्षति

राजधानीसहितका विभिन्न शहरमा भएका आगजनी र तोडफोडबाट खरबौँ बराबरको पूर्वाधार ध्वस्त भएको छ। बजार, यातायात साधन, सरकारी भवनदेखि निजी घरपरिवारसम्म क्षतिग्रस्त भएका छन्। यस क्षतिको असर निकट भविष्यमा अर्थतन्त्रलाई थप जटिल बनाउने विशेषज्ञहरूको ठम्याइ छ।

हिंसाको दुवै रूप चिन्ताजनक

प्रदर्शनमा राज्यको बल प्रयोगले ज्यान गुमाउनु र आन्दोलनकारी भीडबाट वृद्ध नेताहरू कुटपिट हुनु—दुवै घटनाले आक्रोश मात्र होइन, विभाजन र वैमनस्यताको बीउ रोपेको देखिन्छ। विशेष गरी सामाजिक सञ्जालमा युवापुस्ताले हिंसा र आगजनीलाई समर्थन वा रमाइलोको रूपमा प्रस्तुत गरिरहेको प्रवृत्तिले दीर्घकालीन अस्थिरताको जोखिम देखाएको छ।

नेतृत्व र दिशाको अस्पष्टता

आन्दोलन सुरुमा जायज आक्रोशको स्वरूपमा देखा परे पनि हाल यसको नेतृत्व र दिशाबारे स्पष्टता देखिएको छैन। आन्दोलनपश्चात् संक्रमणकालीन राजनीतिक मार्गचित्र कोर्ने बेला सक्षम, दृष्टिवान् नेतृत्व उदाएन भने देश अझ ठूलो अनिश्चिततामा फस्ने चिन्ता बढेको छ।

राजनीतिक दलहरूको भूमिकामाथि प्रश्न

विश्लेषकहरूका अनुसार वर्तमान संकटमा सरकारको अहंकार, प्रमुख दलहरूको सत्ता–केन्द्रित राजनीति र प्रतिपक्षको गैरजिम्मेवार भूमिकाले पनि योगदान गरेको छ। एमाले अध्यक्ष केपी ओलीदेखि सत्तासाझेदारीमा रहेका कांग्रेस र अन्य दलहरू सबै समान रूपमा आलोचनाको घेरामा परेका छन्।

अत: दुई दिनमा देखिएको अराजकता र ठूलो मानवीय क्षतिले मुलुकलाई गम्भीर मोडमा पुर्याएको छ। हिंसा र प्रतिहिंसाको संस्कृतिलाई रोक्न, अराजकतालाई नियन्त्रण गर्न र विवेकशील नेतृत्व खडा गर्न सकिएन भने नेपालको राजनीतिक यात्रामा अझ गहिरो संकट देखा पर्ने विज्ञहरूको चेतावनी छ।

Here’s an essay tailored for a Class 10 board exam (SEE), with around 300 words to match the depth and structure expected at that level:

Discipline is one of the essential trait that helps people achieve success, self-control, and responsibility. To put it simply, discipline is the process of putting bad deeds behind oneself, growing in moral character, being ethical, thinking positively, being professional, charitable, and acting morally. Discipline is crucial for young people, particularly students, as it helps them form positive habits and gets them ready for the future. In order to make students understand the values of diligence, curiosity, intelligence, punctuality and academic success requires discipline. A well-behaved student pays attention in class, studies consistently, and completes his/her assignment on time. Disciplined students prevent themselves from last-minute stress  before tests by practicing time management efficiently. Maintaining discipline helps students learn more and more which in turn increases their confidence. Additionally, discipline in academics helps students learn how to prioritize the task which is most essential in adult life.

Discipline is equally important in personal life too. It enhances the person's ability to resist distractions. Practicing discipline helps everyone to follow healthy routines like exercising regularly, eating balanced diet, and get required sleep. This supports in physical health as well as mental and social health.

In societal context, discipline is the master key to create a better environment. By following social norms and ideologies, a person can contribute to safety and harmony. For instance, in a neighborhood if people manage the garbage properly, it reduces the risk of health issues and tension between people. Discipline fosters cooperation between people and helps in societal development.

In conclusion, discipline is a guiding principle that leads to a fulfilling and balanced life. It is essential for personal growth, academic success and societal harmony. Developing discipline from a young age equips individuals to face life’s challenges, ultimately leading them to a successful and meaningful life.

Marie was born in 1867 in Warsaw, Poland, where her father was a professor of physics. At an early age, she displayed a brilliant mind and a blithe personality. Her great exuberance for learning prompted her to continue with her studies after high school. She became disgruntled, however, when she learned that the university in Warsaw was closed to women. Determined to receive a higher education, she defiantly left Poland and in 1891 entered the Sorbonne, a French University, where she earned her Master's degree and doctorate in Physics.

Marie was fortunate to have studied at the Sorbonne with some of the greatest scientists of her day, one of whom was Pierre Curie. Marie and Pierre were married in 1895 and spent many productive years working together in the Physics laboratory. A short time after they discovered radium, Pierre was killed by a horse-drawn wagon in 1906. Marie was stunned by this horrible misfortune and endured heart breaking anguish. The fact that she had two young daughters to raise by herself greatly increased her distress.

Marie was asked to succeed her husband as a Physics professor at the Sorbonne. She was the first woman to be given a professorship at the world-famous university. In 1911 she received the Nobel Prize in chemistry for isolating radium. Although she eventually suffered a fatal illness from her long exposure to radium, she never became disillusioned about her work.

→Lost Child Rescued After 3 Days

By a local correspondent, Jhapa

1 June, 2025

A 6-year-old child (named Mr. ABC Rai) who went missing while he was going home from his school through a forest road, was ultimately rescued by a group of woodcutters.

The child was reportedly playing with his classmates during the lunch break when he wandered off unnoticed. Local authorities, along with concerned residents, launched a comprehensive search operation for three days to locate the child. The community was urged to remain vigilant and report any suspicious activity to the authorities.

A miracle happened after 3 days. A group of woodcutters rescued the child from the dense forest where he is reported to have taken the shortcut before went missing. The parents as well as the local authorities and the members of public greatly thanked the woodcutters for rescuing the child.

This incident reminds the school staff to be vigilant all the time in the school by keeping the main gate always locked.

Dear Ankit,

I am sure this letter finds you well and in good spirits. I wanted to express my reflections on an issue that has been occupying my thoughts recently - the movement of young people and professionals from Nepal to foreign countries.

Every year, a large number of our countrymen leave Nepal in search of better opportunities overseas. Although this migration can foster personal and professional advancement for those individuals, it also has several extensive consequences for our home nation. On the positive side, the remittances sent back to Nepal by these emigrants make a substantial contribution to our economy. Nevertheless, the adverse effects cannot be overlooked. The brain drain resulting from the departure of skilled professionals causes a shortage of talent in essential sectors such as healthcare, education, and engineering. This impedes our nation's growth and advancement.

In order to tackle these challenges, I think it is essential to develop more opportunities within Nepal. The government ought to allocate resources towards education, healthcare, and infrastructure to foster a supportive atmosphere for progress. Furthermore, promoting entrepreneurship and aiding small enterprises can generate employment and lessen the urge to migrate. We, as members of society, should likewise cultivate a sense of patriotism and inspire our young people to take part in the advancement of the nation.

I'm eager to hear your opinions on this issue. Let's collaborate to discover solutions that will benefit our cherished Nepal. Stay safe and take care.

Warm regards — Your friend Anjan
