Dear Editor
Through the coloumns of your esteemed newspaper, I would like to draw the attention of the people towards the burning issue of dowry and its ill-effects on our society.

The dowry system is a social evil. In India many of the traditional customs have been given up, but the custom of dowry has not only continued, but flourished over the years.In spite of increase in the literacy rate, education and modernization, we have not been able to eradicate this problem from our society. Even today, daughters are given furniture, crockery, electronic items, jewellery, cars, flats etc. in order to ensure their security. Initially dowry was given to support the new couple, but with the passage of time marriage has become an occasion for blatant selling of the bridegroom. The ill-effects of this problem include the neglect of daughters, sex-selective abortion, female infanticide, and the harassment, abuse etc. When demands for dowry are not met, the bride is subjected to torture, and often even killed.

प्रश्न १: प्रकृति में आए असंतुलन का क्या परिणाम हुआ?

उत्तर : प्रकृति में आए असंतुलन का यह परिणाम हुआ कि कोई भी प्रदूषण के प्रभाव से अछूता नहीं रहा | पक्षियों ने बस्तियों से भागना शुरू कर दिया | गर्मियों में ज़्यादा गर्मी, बेवक्त की बरसातें, भूकंप, सैलाब, तूफ़ान, ज़लज़ले और नित नए रोगों के रूप में हम इस असंतुलन के प्रभाव को स्पष्ट देख सकते हैं | प्रकृति की सहनशक्ति की एक सीमा होती है और जब उसके साथ अत्यधिक छेड़छाड़ की जाती है, तो प्रकृति में असंतुलन पड़ जाता है | इससे पर्यावरण पर बुरा प्रभाव पड़ता है |

प्रश्न २: लेखक की माँ ने पूरे दिन रोज़ा क्यों रखा ?
 
उत्तर : लेखक की माँ ने पूरे दिन का रोज़ा रखा ताकि वह अपनी भूल का प्रायश्चित कर सके | लेखक के ग्वालियर के घर में एक कबूतर के जोड़े ने अपना घोंसला बना लिया था, जिसमें रखे दो अण्डों में से एक बिल्ली ने तोड़ दिया था | लेखक की माँ को यह देखकर बहुत दुःख हुआ | उन्होंने स्टूल पर चढ़कर दूसरे अंडे को बचाने की कोशिश की परन्तु वह अंडा उनके हाथ से गिरकर टूट गया | कबूतरों की परेशानी और दुःख देखकर माँ की आँखों में आँसू आ गए | उस दुःख में उन्होंने कुछ भी खाया-पीया नहीं और बस रोती रहीं | खुदा से माफी माँगने के लिए उन्होंने पूरे दिन का रोज़ा रखा और नमाज़ पढ़कर इस गलती को माफ़ करने की दुआएँ मांगती रही |
