Answer»

पूर्ण स्वराज्य का जुलूस निकल रहा था। कुछ युवक, कुछ बूढ़े, कुछ बालक झंडियाँ और झंडे लिये वंदेमातरम् गाते हुए माल के सामने से निकले। दोनों तरफ दर्शकों की दीवारें खड़ी थीं, मानो उन्हें इस लक्ष्य से कोई सरोकार नहीं हैं, मानो यह कोई तमाशा है और उनका काम केवल खड़े-खड़े देखना है।शंभूनाथ ने दूकान की पटरी पर खड़े होकर अपने पड़ोसी दीनदयाल से कहा-सब के सब काल के मुँह में जा रहे हैं। आगे सवारों का दल मार-मार भगा देगा।दीनदयाल ने कहा-महात्मा जी भी सठिया गये हैं। जुलूस निकालने से स्वराज्य मिल जाता तो अब तक कब का मिल गया होता। और जुलूस में हैं कौन लोग, देखो-लौंडे, लफंगे, सिरफिरे। शहर का कोई बड़ा आदमी नहीं।मैकू चट्टियों और स्लीपरों की माला गरदन में लटकाये खड़ा था। इन दोनों सेठों की बातें सुनकर हँसा।शंभू ने पूछा-क्यों हँसे मैकू? आज रंग चोखा मालूम होता है।मैकू-हँसा इस बात पर जो तुमने कही कि कोई बड़ा आदमी जुलूस में नहीं है। बड़े आदमी क्यों जुलूस में आने लगे, उन्हें इस राज में कौन आराम नहीं है? बँगलों और महलों में रहते हैं, मोटरों पर घूमते हैं, साहबों के साथ दावतें खाते हैं, कौन तकलीफ है ! मर तो हम लोग रहे हैं जिन्हें रोटियों का ठिकाना नहीं। इस बखत कोई टेनिस खेलता होगा, कोई चाय पीता होगा, कोई ग्रामोफोन लिए गाना सुनता होगा, कोई पारिक की सैर करता होगा, यहाँ आये पुलिस के कोड़े खाने के लिए? तुमने भी भली कही?शंभू-तुम यह सब बातें क्या समझोगे मैकू, जिस काम में चार बड़े आदमी अगुआ होते हैं उसकी सरकार पर भी धाक बैठ जाती है। लौंडों-लफंगों का गोल भला हाकिमों की निगाह में क्या जँचेगा?मैकू ने ऐसी दृष्टि से देखा, जो कह रही थी-इन बातों के समझने का ठीका कुछ तुम्हीं ने नहीं लिया है और बोला-बड़े आदमी को तो हमी लोग बनाते-बिगाड़ते हैं या कोई और? कितने ही लोग जिन्हें कोई पूछता भी न था, हमारे ही बनाये बड़े आदमी बन गये और अब मोटरों पर निकलते हैं और हमें नीच समझते हैं। यह लोगों की तकदीर की खूबी है कि जिसकी जरा बढ़ती हुई और उसने हमसे आँखें फेरीं। हमारा बड़ा आदमी तो वही है, जो लँगोटी बाँधे नंगे पाँव घूमता है, जो हमारी दशा को सुधारने के लिए अपनी जान हथेली पर लिये फिरता है। और हमें किसी बड़े आदमी की परवाह नहीं है। सच पूछो तो इन बड़े आदमियों ने ही हमारी मिट्टी खराब कर रखी है। इन्हें सरकार ने कोई अच्छी-सी जगह दे दी, बस उसका दम भरने लगे।दीनदयाल-नया दारोगा बड़ा जल्लाद है। चौरास्ते पर पहुँचते ही हंटर लेकर पिल पड़ेगा। फिर देखना, सब कैसे दुम दबाकर भागते हैं। मजा आयेगा।जुलूस स्वाधीनता के नशे में चूर चौरास्ते पर पहुँचा तो देखा, आगे सवारों और सिपाहियों का एक दस्ता रास्ता रोके खड़ा है।सहसा दारोगा बीरबल सिंह घोड़ा बढ़ा कर जुलूस के सामने आ गये और बोले-तुम लोगों को आगे जाने का हुक्म नहीं है।जुलूस के बूढ़े नेता इब्राहिम अली ने आगे बढ़कर कहा-मैं आपको इत्मीनान दिलाता हूँ, किसी किस्म का दंगा-फसाद न होगा। हम दूकानें लूटने या मोटरें तोड़ने नहीं निकले हैं। हमारा मकसद इससे कहीं ऊँचा है।बीरबल-मुझे यह हुक्म है कि जुलूस यहाँ से आगे न जाने पाये।इब्राहिम-आप अपने अफसरों से जरा पूछ न लें।बीरबल-मैं इसकी कोई जरूरत नहीं समझता।इब्राहिम-तो हम लोग यहीं बैठते हैं। जब आप लोग चले जायँगे तो हम निकल जायँगे।बीरबल-यहाँ खड़े होने का भी हुक्म नहीं है। तुमको वापस जाना पड़ेगा।इब्राहिम ने गंभीर भाव से कहा-वापस तो हम न जायेंगे। आपको या किसी को भी, हमें रोकने का कोई हक नहीं। आप अपने सवारों, संगीनों और बंदूकों के जोर से हमें रोकना चाहते हैं, रोक लीजिए, मगर आप हमें लौटा नहीं सकते। न जाने वह दिन कब आयेगा, जब हमारे भाई-बंद ऐसे हुक्मों की तामील करने से साफ इन्कार कर देंगे, जिनकी मंशा महज कौम को गुलामी की जंजीरों में जकड़े रखना है।बीरबल ग्रेजुएट था। उसका बाप सुपरिंटेंडेंट पुलिस था। उसकी नस-नस में रोब भरा हुआ था। अफसरों की दृष्टि में उसका बड़ा सम्मान था। खासा गोरा चिट्टा, नीली आँखों और भूरे बालों वाला तेजस्वी पुरुष था। शायद जिस वक्त वह कोट पहन कर ऊपर से हैट लगा लेता तो वह भूल जाता था कि मैं भी यहाँ का रहनेवाला हूँ। शायद वह अपने को राज्य करनेवाली जाति का अंग समझने लगता था; मगर इब्राहिम के शब्दों में जो तिरस्कार भरा हुआ था, उसने जरा देर के लिए उसे लज्जित कर दिया। पर मुआमला नाजुक था। जुलूस को रास्ता दे देता है, तो जवाब तलब हो जायेगा; वहीं खड़ा रहने देता है, तो यह सब न जाने कब तक खड़े रहें। इस संकट में पड़ा हुआ था कि उसने डी. एस. पी. को घोड़े पर आते देखा। अब सोच-विचार का समय न था। यही मौका था कारगुजारी दिखाने का। उसने कमर से बेटन निकाल लिया और घोड़े को एड़ लगा कर जुलूस पर चढ़ाने लगा। उसे देखते ही और सवारों ने भी घोड़ों को जुलूस पर चढ़ाना शुरू कर दिया। इब्राहिम दारोगा के घोड़े के सामने खड़ा था। उसके सिर पर एक बेटन ऐसे जोर से पड़ा कि उसकी आँखें तिलमिला गयीं। खड़ा न रह सका। सिर पकड़ कर बैठ गया। उसी वक्त दारोगा जी के घोड़े ने दोनों पाँव उठाये और जमीन पर बैठा हुआ इब्राहिम उसकी टापों के नीचे आ गया। जुलूस अभी तक शांत खड़ा था। इब्राहिम को गिरते देख कर कई आदमी उसे उठाने के लिए लपके; मगर कोई आगे न बढ़ सका। उधर सवारों के डंडे बड़ी निर्दयता से पड़ रहे थे। लोग हाथों पर डंडों को रोकते थे और अविचलित रूप से खड़े थे। हिंसा के भावों में प्रभावित न हो जाना उसके लिए प्रतिक्षण कठिन होता जाता था। जब आघात और अपमान ही सहना है, तो फिर हम भी इस दीवार को पार करने की क्यों न चेष्टा करें? लोगों को खयाल आया शहर के लाखों आदमियों की निगाहें हमारी तरफ लगी हुई हैं। यहाँ से यह झंडा लेकर हम लौट जायँ, तो फिर किस मुँह से आजादी का नाम लेंगे; मगर प्राण-रक्षा के लिए भागने का किसी को ध्यान भी न आता था।
