Actual problems in virtual world

Image
The world has become more virtual these days, thanks to social media. It is quite difficult to distinguish between real and fake. Apart from this, most of us are least bothered about the possible consequences of likes, shares and comments in social media. Let us begin with a story. A boy challenged his friend to gather a crowd around him without speaking a single word. His friend accepted the challenge and went to an open space on the roadside and started gazing at the sky. Passersby saw this strange act but they didn’t care. Few minutes passed, the boy continued gazing and then people began to observe. A few more minutes later, there was a crowd of people all gazing at the sky! It is indeed very easy to mislead someone and in this age of social media it is even easier to mislead thousands and thousands of people at a time. We don’t think before we share, we don’t care about what we share but we just like, click and share. A massive portion of the users in social media are definitely l...

যখন আবার দেখি তোমায় !!

Image
দেখেছি আজ আবার স্বপ্নের সেই ছবি তার । মনে পরেছে আমার  সেই পরিহাস ভালোবাসার । সবই মিথ্যে, সবই অহেতুক কেন বৃথা করি অভিযোগ । সেন অকারণে, অযথা সন্ধানে বসে থাকি পথ চেয়ে বার বার ! বুঝিতে চাই তবু বুঝিতে না পারি, ভুলিতে চাই তবু ভুলিতে কি পারি ? কেন আসে মনে কিছু না জানি স্বপ্নের সেই ছবি বারংবার !!

A poem written by me ...

Image
A shattered dream silently screams "Let this not happen again !" A watery eye cries in pain- "I was a fool to see that smile- The smile that made me dream". A disturbed mind doesn't care to feel, Says, its feelings had never been a big deal ! A confused brain tries its best To erase that lovely face- The beauty which reminds it of pain. A sharp memory laments in vain "Why do I have to remember forever The tales of pleasure and pain?" A broken heart still somehow beats For life has much more to offer Than unfulfilled wishes and shattered dreams.

Awesome Rabindra Sangeet !!

I don't know whether you will remember me or not, Time and again I use to come to you And sing for you without any reason... Time goes by but so long as I live I have one desire .. Whenever I happen to meet you on my way, I want to see a cute smile of surprising happiness on your face... And that is why I keep singing for you without any reason !!                                                                         - DS মনে রবে কি না রবে আমারে সে আমার মনে নাই। ক্ষণে ক্ষণে আসি তব দুয়ারে, অকারণে গান গাই॥ চলে যায় দিন, যতখন আছি পথে যেতে যদি আসি কাছাকাছি তোমার মুখের চকিত সুখের হাসি দেখিতে যে চাই-- তাই অকারণে গান গাই॥
