‘Dead men do not require footpaths.’ Explain on the basis of the story. ‘मृत लोगों को पगडंडियों की आवश्यकता नहीं होती है। कहानी के आधार पर व्याख्या कीजिए। 

Answer»

There was an almost disused path across the school-ground. As it connected the village shrine with their place of burial, the villagers believed that their dead relatives departed by that path and visited them by that path. The children that were about to born would come by that path. So the village priest wanted the new headmaster of the school to accept this belief and re-open the path which he had closed. But the headmaster told the village priest that dead men did not require such paths and that it was an absurd idea which he would like their children to laugh at. The headmaster suggested constructing another path, going around their premises. He said that the ancestors would not find the little detour too burdensome.

विद्यालय के मैदान के आर-पार एक ऐसा रास्ता था जिसे प्रायः काम में नहीं लिया जाता था। चूँकि रास्ता गाँव के पूजा स्थल को कब्रिस्तान से जोड़ता था, अतः गाँव के लोगों को ऐसा विश्वास था कि उनके मृत रिश्तेदार इस मार्ग से उनसे मिलने आते थे। पैदा होने वाले बच्चे उसी रास्ते से आएंगे। इसलिए गाँव का पादरी चाहता था कि स्कूल को नया प्रधानाध्यापक इस विचार से सहमत हो जाए और बन्द मार्ग को खोल दे। परन्तु प्रधानाध्यापक ने गाँव के पादरी से कहा कि मृत लोगों को एसे रास्तों की जरूरत नहीं होती है और यह कि यह एक बेतुका विचार था जिस पर वह चाहेगा कि उनके बच्चे हँसें प्रधानाध्यापक ने दूसरी पगडंडी बनाने की सलाह दी जो उनके परिसर के चारों ओर होकर गुजरे उसने कहा कि पूर्वजों को थोड़ा-सा चक्करदार मार्ग इतना ज्यादा भारी नहीं लगेगा।

5.

What happened when the school teachers attempted to close the path? जब विद्यालय के शिक्षकों ने मार्ग बन्द करने का प्रयास किया तो क्या हुआ?

Answer»

When the school teachers attempted to close the path, the village priest called on the headmaster and reasoned with him to reopen the path. He said that it was wrong to do so. It was an important path for the villagers.

जब विद्यालय के शिक्षकों ने मार्ग बन्द करने का प्रयास किया तो गाँव का पादरी प्रधानाध्यापक से मिलने आया और उसे मार्ग पुनः खोलने के लिए समझाया। उसने कहा कि ऐसा करना गलत था। गाँव वालों के लिए यह महत्वपूर्ण रास्ता था।

Why were the school building and hedges ruined? विद्यालय भवन तथा बाड़ को क्यों नष्ट कर दिया गया?

Answer»

The Headmaster Michael Obi closed the path that passed across the school compound. The village priest suggested reopening the path but Michael refused to do so. According to Obi, it was a baseless idea and the whole purpose of the school was to eradicate just such beliefs. He did not allow the reopening of the path. Three days later a young woman died in the village in childbirth. A diviner was consulted who prescribed heavy sacrifices to pacify ancestors who were insulted by the fence. Next day the beautiful hedges were torn up right around the school, the flowers were trampled to death and one of the school buildings was pulled down. It was reported that the misguided zeal of the new headmaster had caused a tribal-war situation between the school and the village.

प्रधानाध्यापक माइकल ओबी ने विद्यालय के मैदान में से होकर गुजरने वाले रास्ते को बन्द कर दिया। गाँव के पादरी ने माइकल से उस रास्ते को पुनः खोलने का सुझाव दिया पर माइकल ने ऐसा करने से मना कर दिया। ओबी के अनुसार यह एक निराधार विचार था तथा विद्यालय का उद्देश्य ऐसे विश्वासों को नष्ट करना था। उसने रास्ते को दुबारा खोलने से मना कर दिया। तीन दिन बाद गाँव में प्रसव के दौरान एक नवयुवती की मृत्यु हो। गई। एक शगुनियाँ से परामर्श लिया गया जिसने बाड़ से अपमानित पूर्वजों की शान्ति के लिए भारी बलिदान करने की सलाह दी। अगले दिन विद्यालय के चारों ओर की सुन्दर बाड़ों के टुकड़े-टुकड़े कर दिए गए, फूलों को कुचल कर नष्ट कर दिया गया और विद्यालय के एक भवन को ढहा दिया गया। यह रिपोर्ट की गई कि नये प्रधानाध्यापक का भ्रमित जोश विद्यालय तथा गाँव के बीच एक जनजातीय झगड़े का कारण बना।

Describe the condition of the Ndume Central School before and after Michael Obi. माइकल ओबी के पहले व बाद की एनड्यूम सेंट्रल स्कूल की स्थिति का वर्णन कीजिए।

Answer»

Before Michael Obi’s appointment, Ndume Central School was an unprogressive school. It was backward in every sense of the word. Mr Obi and his wife put their whole attention into the task of improving it. He had two aims – a high standard of teaching and to turn the school campus into a place of beauty and worked accordingly. Their dream-gardens came to life with the coming of the rains and blossomed. Beautiful hibiscus and allamanda hedges in brilliant red and yellow marked out the carefully tended school compound from the rank neighbourhood bushes. He planted heavy sticks closely across the path at the two places where it entered and left the school premises. These were further strengthened with barbed wire. In this way, he closed the path that crossed the school campus.

माइकल ओबी की नियुक्ति से पूर्व एनड्यूम सेन्ट्रल स्कूल एक पिछड़ा हुआ विद्यालय था। यह प्रत्येक तरह से पिछड़ा हुआ था। मि. ओबी और उसकी पत्नी ने विद्यालय में परिवर्तन लाने के लिए अपना पूरा ध्यान उसे सुधारने में लगा दिया। उसके दो उद्देश्य थे- शिक्षण का उच्च स्तर तथा विद्यालय परिसर को एक सुन्दर स्थान बनाना और तदनुरूप कार्य भी किया। वर्षा के आने से तथा फूलों के खिलने से उनका स्वप्न सच हो गया। चमकीले लाल और पीले सुन्दर गुड़हल और अलमान्डा की बाड़े सुव्यवस्थित विद्यालय मैदान को अत्यधिक बढने वाली समीपवर्ती झाड़ियों से अलग दिखा रही थीं। उसने रास्ते के आर-पार दो स्थानों पर जहाँ यह विद्यालय परिसर में प्रवेश करता और जहाँ इसे छोड़ता था भारी डण्डे गाड़ दिये गए। इन्हें काँटेदार तारों से और मजबूत कर दिया गया। इस तरह से उसने विद्यालय को पार करने वाले रास्ते को बंद कर दिया।

He sometimes surprised people with sudden bursts of physical energy. His deep-set eyes had an extraordinary power of penetration. He was only twenty-six but looked thirty or more. He worked hard for the Ndume Central School and changed it according to his aim.
