Indian Beauti

IT IS TRUE that modern posh life and western style of living has made Indian women to shed down their traditional outlook to some extent. Their dressing system has changed.They move out more than they did in earliier days, etc. Some modern girls have drinking and smoking habits also.But the percentage of such women is still very very less.-not even 1% of the total women percentage in india.Majority of our ladies are still god-fearing ,kind hearted, and like to have sex with their life partner only.Family life is still a major concern for Indian woman.By these characteristics, their beauty has increased,as it brings a cultural look.

The Dress

Saree is most suited dress for traditional Indian women. But churidar is also equally respected and preferred outfit.Skirts are not usually worn by majority of married indian women, though it is not a bar.

Jeans and Shirts

Yes, that too is seen on Indian ladies now a days. But it is not yet a village level dress. it is used , to a large extent, by educated ladies, or college students, living in cities and big towns.
Wearing a loose top-like jubba(shirt) is now on the way of getting accepted as a honourable outfit.In Big cities and metropolis, grown up ladies also wear jeans and tight shirts, which gives a sexy look. it can not be denied now that younger generation if indian women, to some extent, are developing a leaning towords sexy dresses. on the influence of western trends.

Beauty and dress

It is a known fact that dress , properly worn, enhances the beauty of a [person. So, Indian ladies have taken care of dressing in their own way, for a long time. In olden timen times, even in Ashrams of saints, it is said that ladies used to decorate themselves, with flowers.Eventoday, flower wearing is perhaps a unique love for Indian ladies.Saree- is the unique outfit of indian ladies, since thousands of years.

Beauty in goddesses

Indian culture has seen its gods and goddesses also as beautiful indivisuals. Lakshmi (goddess of wealth), Saraswathi( goddess of knowledge and learning), Parvathi( wife of Lord Shiva), are all beautiful. Prayer verses praising there beauty are being sung from thousands of years. It is said, there beauty is the symbol of their bounty.
Sathyam, Shivam, SundaramIndian culture has considered beauty as the expression of Godliness. ‘That is beautiful, which is favorable to all’-so says a Samskrit hymn.The actual meaning of the word ‘Shivam’ is-favorable.So the beauty is that- which does good to all. Otherwise, even though the features, color, etc are good, but person has bad intentions, it is not beauty.

New currency symbol : INDIA IS DEVELOPING

For something that's really just a bit of a squiggle - a combination of the letters denoting the R sound in two scripts, Devanagari and English - the new symbol for the Indian rupee carries a lot of weight. As it stands now, only four currencies have symbols that are synonymous with them internationally - the US dollar, British pound, Japanese yen and European euro. They connote strong economies and global currencies. That should make the power of symbolism clear, and the benefits of India joining this exclusive club.
Admittedly, the Indian economy, despite its heavyweight status on the basis of sheer size, is not yet as globally relevant as some of the others. But it's swiftly getting there. At over a trillion dollars, it is a powerhouse not just in Asia but internationally. Its performance during the global recession has only enhanced its standing. Factor in its G20 membership and expanding international trade, service and investment flows, and its cachet has never been as high. What better time to exploit this and play up India's global face and the weight of its economy by coining this symbol? 


The object of the entire exercise is to leverage the prestige and the symbolism that having a monetary symbol denotes. It will also be useful shorthand for distinguishing the Indian rupee from the similarly named currencies of its South and East Asian neighbours. India's political leadership is often criticised for lacking ambition for the country. Launching the rupee symbol, however, sends a clear signal about the direction in which it wants to take India and the role India sees for itself in the global economy and world affairs. When so much in Indian politics is insular, this needs to be welcomed. Symbols are important too. The rupee symbol establishes a brand for India which can help shape reality, especially when leveraged well with appropriate actions.

MY DEAR BROTHER

umar bhar chaha ki ye asma hamara hota,
kash khwabo ka v koi kinara hota.

Bus ye soch kar n roka us musafir ko,
 
Ki dur jata hi kyon agar wo hamara hota.
In the memory of my sweet brother.

Who is more punishable - Afzal Guru OR KASAB ?

Although his ploy to cut short the 26/11 trial with his "confession" has not worked, Ajmal Amir Kasab's collateral plea for death sentence opens up the possibility of his being hanged before Parliament attack convict Afzal Guru.

This is because while Guru's mercy petition is caught in the home ministry's red tape with little prospect of being disposed of any time soon, no such dilatory factor may come in the way of Kasab's execution if he sticks by his plea for capital punishment.

For, in the event of a very likely death sentence to him at the end of the ongoing fast-track trial, Kasab is set to create an unusual, if not unprecedented, situation if he does not exercise his option of filing an appeal against the judgment.

In that scenario, the matter will still go to the Bombay high court in the form of a reference because the criminal procedure code requires a death sentence to be confirmed by it.

Once the high court disposes of the reference, there will not be any more impediments to his execution.
The government can proceed with his execution even if the appeals filed by his two Indian co-accused, who are alleged to have provided logistical support to the terrorists who had come from Pakistan, are pending before the high court or SC.

After the trial court pronounces its verdict, Kasab's case can well be separated not only due to the public clamour for his execution but also because the possibility, however thin, of his co-accused being acquitted will not detract from his own conviction, whether it is based on his confession or not. Since the trial court is anyway dealing with the 26/11 case with extraordinary speed (it is already at an advanced stage of the trial for a crime that took place barely eight months ago), the criminal justice system may welcome any helping hand from Kasab to expedite the execution of the death sentence.

It may mark a departure from the trend of condemned prisoners languishing on death rows, indefinitely, on account of the notorious laxity on the part of the home ministry in processing mercy petitions addressed to the President under a Constitutional provision.

The home ministry is yet to take up Afzal's mercy petition although it has been pending for three years. It is sitting on a bunch of 28 mercy petitions filed by, among others, those convicted in the Rajiv Gandhi murder case, seeking commutation of capital punishment to life sentence. Afzal reportedly stands 22nd in that list of 28.

Unless Kasab does a somersault on his plea for death sentence, he is unlikely to join this queue for commutation before the home ministry.
