How was the king’s justice fair?राजा का निर्णय किस प्रकार से निष्पक्ष होता था?

Answer»

In the king’s method of justice crime was decided by the two doors-the tiger or the lady behind them each.The tiger punished the accused and the lady rewarded him. Everything was dependent on the chance or fate.The tiger or the lady did come out of the same door every time. Nobody was sure what would happen at the next moment. Still people were happy because justice was done instantly.

राजा के न्याय विधान के अनुसार अपराध का निर्णय दो दरवाजों के माध्यम से होता था कि वह दोषी है। अथवा निर्दोष, जिसमें से एक के पीछे बाघ होता था तो दूसरे के पीछे नारी। बाघ उस दोषी व्यक्ति को सजा देता था जबकि नारी पुरस्कार के रूप में होती थी। सब कुछ भाग्य अथवा अवसर पर निर्भर करता था। बाघ अथवा नारी कभी भी एक ही दरवाजे से निकल कर बाहर आए यह आवश्यक नहीं था। कोई भी इस बात को लेकर आश्वस्त नहीं था कि अगले क्षण क्या होने वाला है। इसके बावजूद लोग खुश होते थे कि आने वाले क्षण में न्याय होने वाला है।

What does the phrase ‘Sad iron bells’ signify?‘लोहे का उदास घंटा’ लोकोक्ति व्यक्त करता है?

Answer»

When the hungry tiger decided the fate of the accused person, there was no chance of his living. The sad iron bells were rung to declare his death.

दोषी के भाग्या का निर्णय जब एक भूखा बाघ निर्धारित करता था तो उसके जिंदा रहने की उम्मीद पूरी तरह से समाप्त हो चुका होता था। लोहे का उदास (दुखद) घंटा बजना उसके मौत को घोषित करता था।

4.

What sharpened the king’s ideas? How did his authority help him?राजा का विचार किस प्रकार से स्वच्छ होता था? उसके सहयोगी किस प्रकार से उसकी सहायता करते थे?

Answer»

The progressiveness sharpened the king’s ideas. He had learnt many good things from them. Still he was not so popular as his Latin neighbors were.The king was a man of exuberant fancy and immense enthusiasm. As a king he had a great deal of authority. No body could question his power. His irritable authority always helped him put some of his fancies into practice.

प्रगतिशीलता राजा के विचार को तेज करने का काम करता था। उसने इससे कई अच्छी बातों को सीखा था। इसके बावजूद वह अपने लेटिन पड़ोसियों से अधिक प्रसिद्ध नहीं हो पाया था। राजा अपनी कल्पनाओं से उल्लासित होने वाला और अत्यंत उत्साही प्रवृति का था। एक राजा होने के नाते वह एक सर्वशक्तिमान प्रशासक था। उसकी शक्ति पर कोई भी प्रश्न नहीं उठा सकता था। उसका चिड़चिड़ापन उसकी कल्पनाओं को हकीकत में ढालने का अवसर प्रदान करता था।

They thought that the princess was bound to fall in love with him. But how it happened was difficult to say. Perhaps her love was dramatic.

राजकुमारी और उस नौजवान के बीच का यह प्रेम-प्रसंग कई महीनों तक गुप्त ढंग से चलता रहा। लेकिन संयोग से इस बात को उसके पिता (राजा) ने जान लिया और उस नौजवान को तत्काल केद कर जेल में डाल दिया। हालंकि वह नवयुवक राजकुमारी की सामाजिक स्थिति से नीचे के स्तर का था, लेकिन वह बहादुर, सुन्दर और नौजवान था। वह उसे आत्मा की अतल गहराइयों से प्रेम करता था। सुनवाई के दिन वहां पहुंचे सभी दर्शक राजकुमारी के उस प्रेमी को देख कर आश्चर्यचकित थे। वे यह सोचते थे कि राजकुमारी तो इससे प्यार करने के लिए वाध्य ही थी। लेकिन ऐसा केसे हुआ, यह कहना अत्यंत ही कठिन था। शायद उनका प्रेम नाटकीय था।

10.

What arrangements did the king make for the young man’s trial?उस नौजवान के मामले की सुनवाई के लिए राजा ने क्या व्यवस्था किया था?

Answer»

For the young man’s trial the king chose the fiercest tiger. He himself selected a lady for the young man.She was one of the most beautiful ladies in the entire country. Even the princess was jealous for her. All the proceedings were controlled by him. The mourners were posted outside the arena. The priests were also ready behind the door. Even facts of the matter did not produce any effect on his arrangements.

उस नौजवान की सुनवाई के लिए राजा ने अत्यंत ही क्रूर बाघ का चयन किया था। उसने स्वयं ही एक नारी का भी चुनाव किया था। वह उसके राज्य की सबसे | सुन्दरतम महिलाओं में से एक थी। जबकि राजकुमारी को भी उससे जलन हो रहा था। सभी प्रक्रियाओं को वह स्वयं ही नियंत्रित कर रहा था। दीर्घा के बाहरी भाग में मातम करने वाले को तैनात किया गया था। पंडित को भी एक अन्य दरवाजे के पीछे तैयार रखा गया था। यहां तक कि सुनवाई के लिए किए गए। सभी महत्त्वपूर्ण व्यवस्था पर संब) विषय की सत्यता का किसी भी प्रकार सेप्रभाव नहीं पड़ा था।

13.

Why was the princess impatient to attend the trial?राजकुमारी उस सुनवाई में भाग लेने के लिए क्यों अत्यधिक उत्सुक हो गई?

Answer»

The princess knew that her lover might ask for some hints about the doors. She had power, influence and gold to know about the secret of the doors. Her lover was well aware that she would discover it and pass on to him. Besides, she also thought that she would be asked for the secret of the door by her lover in the arena. In her father method of justice there was no provision of escape. It was a choice between death and reward. So, she was impatient to attend the trial.

वह जानती थी कि उसका प्रेमी उससे दरवाजों के मामले में कोई संकेत पाना चाहेगा। उसके पास मामले को प्रभावित करने की क्षमता, राज्याक्ति और प्रचूर मात्रा में सोना है जिसकी सहायता से वह दरवाजे के गुप्त रहस्य को जान सकती है। वहीं उसका प्रेमी इस बात से पूरी तरह से अवगत था कि वह इसे जान जाएगी और उसे बता देगी। इसके साथ ही वह यह भी सोचती थी कि उसका प्रेमी उससे उस दीर्घा में इन दरवाजों के गुप्त रहस्य के बारे में पूछ सकता है। उसके पिता के न्याय विधान के अनुसार दंड से बच निकलने का कोई भी दूसरा रास्ता नहीं था। यह तो मौत अथवा पुरस्कार के रूप में मिलना ही था,अतः उसके लिए यह महत्त्वपूर्ण हो गया था कि वह उस सुनवाई में भाग ले।

14.

How was the princess’ decision serious for her?राजकुमारी का निर्णय उसके लिए क्यों महत्त्वपूर्ण था?

Answer»

The princess fell in love with a young man. The young man loved her deeply. But he was a commoner. Unfortunately the king came to know about their love affairs and put the young man in the prison. He was to be tried in the arena. Anything might happen with him. The princess did not like him to be killed by a hungry tiger. She also had no desire to see him to be married with the lady behind the door. So, it was a crucial moment for her.

राजकुमारी अपने ही देश के एक नौजवान से प्यार करने लगी। वह नौजवान भी उसे बेहद प्यार करता था। लेकिन वह एक सामान्य नागरिक था। संयोग से राजा को इन दोनों के प्रेम-प्रसंग को पता चल गया और उसने उस यवक को केद कर जेल में डाल दिया। उसकी भी सुनवाई उसी दीर्घा में होनी थी। उसके साथ कुछ भी हो सकता था। राजकुमारी यह नहीं चाहती थी कि उसका प्रेमी एक भूखे बाघ के द्वारा मारा जाय। लेकिन उसकी यह भी इच्छा नहीं थी कि उसके प्रेमी का विवाह किसी दूसरी लड़की के साथ हो जो दरवाजे के पीछे खड़ी थी। इसलिए यह उसके लिए बड़ा ही कठिन समय था।

15.

16.

What did the princess feel in her dreams?राजकुमारी ने अपने सपने में क्या अनुभव किया?

Answer»

The princess was frightened by her dreams. The horror of the dream made her restless. She was unable to bear the scene of her lover being killed by a hungry tiger. In her dreams she often covered her face with her hands. She was well aware that in her father’s method of justice only fate of the accused decided death or reward as punishment for him. There was no escape for her lover. As she was scared, she tried to escape the cruelty by covering her face.

राजकुमारी अपने सपने से डर गई। सपने के उस भय ने उसे बेचैन कर दिया। वह अपने प्रेमी को एक भूखे बाघ के द्वारा मार कर खाए जाने के विभीत्स दृश्य को नहीं बरदास्त कर सकती थी। इस भयानक सपने के भय से उसने अपने चेहरे को नींद में ही अपने दोनों हाथों से ढक लिया। वह अपने पिता के इस न्याय विधान से पूरी तरह परिचित थी कि अभियुक्त के निर्दोष अथवा दोषी होने का निर्णय पूरी तरह से उसके अपने भाग्य पर निर्भर था जिसके परिणामस्वरूप उसे पुरस्कार अथवा सजा दिया जाता था। उसके प्रेमी के सामने भी इससे निकलने का कोई रास्ता नहीं था। इसके कारण जो उसके मुंह से चीख निकला, उस क्रूर सपनों की परिधि से बाहर निकलने के लिए उसने अपने चेहरे को अपने हाथों से ढक लिया।

17.

The princess was bound to fall in love with this handsome man. But nobody could change his fate. His misfortune had brought him to the terrible arena.

सुनवाई के दिन वह दीर्घा पूरी तरह से लोगों से भरा था। जब संकेत दिया गया तो राजकुमारी के प्रेमी ने दीर्घा में प्रवेश किया। लोग उसे देखकर अचंभित थे क्योंकि वह अत्यधिक सुन्दर और आकर्षक व्यक्तित्व वाला था। लोग इस बात से अचंभित थे कि इतने सुन्दर व्यक्ति को उनके सामने लाया गया है। राजकुमारी तो इस सुन्दर पुरुष के साथ प्रेम करने के लिए वाध्य थी। लेकिन कोई भी उसक भाग्या को नहीं बदल सकता है। उसका दुर्भाग्य ने ही उसे इस भयावह दीर्घा में ला खड़ा किया है।

18.

How did the element of uncertainty make the trial interesting for the audience?दर्शकों के सामने किस प्रकार से अनिश्चितती सुनवाई को और भी मनोरंजक बनाता था?

Answer»

The king’s method of justice was unique. The fate of the accused was decided by two doors. One door had a beautiful lady behind and the other door had a hungry tiger behind it. The audience were not certain what would happen the next moment. The lady or the tiger never came out of the same door every time. As the secrets of the doors was full of suspense, it was interesting for the audience. The fate of the accused always decided the trial.

राजा का न्याय करने का ढंग अपने-आप में निराला था। अभियुक्त के भाग्य का निर्णय दो दरवाजों के माध्यम से होता था। एक दरवाजे के पीछे एक सुन्दर नारी होती थी और दूसरे दरवाजे के पीछे एक भूखा दुर्दात बाघ रहता था। दर्शक इस बात से निश्चिंत नहीं हो सकते थे कि अगले क्षण क्या होने वाला है। हमेशा एक ही दरवाजे से न ता नारी निकलती थी और न ही बाघ निकलता था। इस तरह से दरवाजे का रहस्य पूरी तरह से आशंकाओं से भरा रहता था, यह दर्शकों के लिए मनोरंजक बनाता था। अभियुक्त का भाग्य हमेशा सुनवाई के बाद ही निर्धारित होता था।

19.

What came out of the door on the day of trial?सुनवाई के दिन दरवाजे के पीछे से क्या निकला?

Answer»

This question is really difficult to be answered. Even the author has left the end to the readers. Anything might have happened with the young man. The princess was jealous of the lady behind the door. She could not see her lover with the beautiful lady. He was to be married with whom the next moment. At the same time she was also helpless to bear the cruelty of the tiger.

इस प्रश्न का उत्तर दे पाना निश्चय ही कठिन था। यहां तक कि लेखक ने भी इसका अंत अपने पाठकों पर छोड़ दिया। उस युवक के साथ कुछ भी हुआ होगा जो स्पष्ट नहीं है। राजकुमारी दरवाजे की पीछे की उस नारी के प्रति जलनशील थी। वह किसी भी हाल में अपने प्रेमी को उस सुन्दर नारी के साथ नहीं देख सकती थी जिसके साथ उसका अगले ही कुछ क्षणों में विवाह हो सकता था। इसके साथ ही उसी क्षण वह उस दुर्दान्त बाघ की क्रूरता को भी बर्दास्त नहीं कर सकती थी।
