Direction: The psychological causes of unhappiness, it is clear, are many and various, but all have something in common. The typical unhappy man, is one who, having been deprived in youth of some normal satisfaction, has come to value this one kind of satisfaction more than any other and has therefore given to his life a one-sided direction, together with a quite undue emphasis upon the achievement as opposed to the activities connected with it. There is, however, a further development which is very common in the present day. A man may feel so completely thwarted that he seeks no form of satisfaction, but only distraction and oblivion. He then becomes a devotee of ‘pleasure'. This is to say, he seeks to make life bearable by becoming less alive. Drunkenness, for example, is temporary suicide the happiness that it brings is merely negative, a momentary cessation of unhappiness.

In mammals, DNA is taken from an adult animal and then it is inserted into an egg cell from another animal. This egg then divides into an embryo. The embryo is then transplanted into a surrogate mother and grown to term. This process has worked in animals like cows, sheep, goats, mice, pigs, rats, cat, monkeys, and horses." The opponents of human cloning say that an embryo at any stage of development is a human life. worthy of protection and any kind of research that entails destroying an embryo is immoral, unethical, no matter how worthy the intent may be.

Siachen must be the strategically most bizarre and futile struggle in the world. Only India and Pakistan would waste lives and hundreds of crores of rupees on it every year. Some in the military argue that controlling Siachen is vital for the security of Kashmir and that Indian presence at Siachen usefully threatens the China-Pakistan Karakoram Highway. Given that hardly anyone can move through the glacier with falling into a crevasse or bursting his lungs and given that the Karakoram Highway is 200 km away, this is absurd. The Pm should forthrightly tell the military that this is complete strategic nonsense and that we should stop sacrificing the lives of jawans in this absurdity. India and Pakistan need to add substance to mostly symbolic diplomacy. Siachen would be a good place to being the march towards substance. Pakistan, for its part, must unequivocally give India MN status. Sir Creek Should be next on the list of substantial problem solving; this also was nearly solved in 1993. Then PM and his Pakistani counterpart need to shore up symbolic with real courage and resolve what is resolvable to create the base the base for a Kashmir settlement in the future.

रिक्शे पर मीरा के साथ हँसती-बोलती ॠतु घर पहुँची। सीढ़ीयाँ चढ़ने लगी तो कुछ झगड़ने की आवाज़े सुनाई दी। ऊपर पहुँची तो देखा, दोनों आजू-बाजू वाली पड़ोसनें झगड़ रही थीं । अपने दरवाज़े के पास खड़ी होकर उसने कुछ देर उनकी बातें सुनीं तो झगड़े का कारण समझ में आया। एक की महरी ने घर साफ़ करके कचरा दूसरी के दरवाज़े की ओर फेंक दिया था, इसी बात का झगड़ा था। ॠतु ने दोनों को समझाया-बुझाया। आख़िरकार कचरा फेंकने वाली महरी को बुलाया गया। उसने झाड़ू थामी और कचरा सीढ़ी की ओर धकेल दिया।फिर वह महरी अंदर चली गई। दोनों पड़ोसनों ने भी अंदर जाकर अपने-अपने द्वार बंद कर लिए ।
ॠतु खड़ी-खड़ी देखती रही।जो सीढ़ी पहले से ही गंदी थी वह और भी गंदी हो गई । रेत का तो साम्राज्य ही था। कहीं बादाम के छिलके पड़े थे तो कहीं चूसी हुई ईख के लच्छे; कहीं बालों का गुच्छा उड़ रहा था तो कहीं कुछ और। मन वितृष्णा से भर उठा। सोचा, इस सीढ़ी से चढ़कर सब अपने घर तक आते हैं, इससे उतरकर दफ्तर, बाजार आदि अपनी इच्छित जगहों पर जाते हैं, पर इसे कोई साफ़ नहीं करता। उलटे सब इस पर कचरा फेंक देते हैं | साझे की सीढ़ी है न ! गंदगी बिखेरने का हक सबको मिला है और साफ़ करने का कर्तव्य किसी का नहीं है। स्वच्छता तो जैसे अनबुझी तृष्णा हो गई।
