Is it help?

Is it Help?

Help is to give or provide what is necessary to accomplish a task or satisfy a need; contribute strength or means to; render assistance to; cooperate effectively with; aid; assist and what not.

"Our prime purpose in this life is to help others." - Dalai Lama




But the story is very different, children are trafficked from their villages and are forced to beg on the urban streets. The children and elderly women begging on the street are often forced beggars – victims of human trafficking. 

For their destination, traffickers chose high wealth concentration cities. There is a physical archetype that traffickers follow when choosing beggars. Often they chose children with handicaps. In a number of reported cases cited in the study traffickers hurt and mutilate beggars on purpose. By maiming and deforming them they create more revenue. A handicapped child earns three times more than a healthy child.

Child begging violates the basic human rights and protection framework of UN Convention on Right of Child (1989). Beggary fits into ILO Convention No.182 on the Worst Forms of Child Labour (1999), as an outcome of illicit human trafficking and is one work that is hazardous physically, emotionally, morally and intellectually to the child’s well-being.

Sleep Paralysis | My Story

At the time of my surgery I had a terrifying question " I suffer from sleep paralysis. I have never had anaesthesia before and I was wondering if sleep paralysis sufferers are more likely to be victims of anaesthesia awareness.  
Should I notify my anesthesiologist about my disorder? "

What I found out was : " Sedation is not general aneasthesia. Sedation will put you in a deep sleep state and you will be simultaneously given pain killers for pain relief. 

General anesthesia would involve paralysing your respiratory muscles and putting in a tube in your wind pipe for artificial ventilation. Dont worry, discuss all this in detail with your anesthesiologist and surgeon. All your doubts should be cleared so that you are not very anxious prior to the procedure. Goodluck." 

What Is Sleep Paralysis?

Sleep paralysis is a phenomenon in which an individual, either during falling asleep (hypnagogia) or awakening (hypnopompia), temporarily experiences an inability to move, speak, or react.

It is a transitional state between wakefulness and sleep, characterized by muscle atonia (muscle weakness). It is often accompanied by unusually powerful and terrifying hallucinations to which one is unable to react due to paralysis, and physical experiences (such as strong current running through the upper body). These hallucinations often involve a person or supernatural creature suffocating or terrifying the individual, accompanied by a feeling of pressure on one's chest and difficulty breathing. Another common hallucination type involves intruders (human or supernatural) entering one's room or lurking outside one's window, accompanied by a feeling of dread. [Wiki] 


What Is Anesthetic Awareness?

Under general anesthesia, a patient is given medications intended to cause unconsciousness and relieve pain. If the medication to render the patient unconscious fails, awareness occurs. In other words, the patient wakes up, becomes aware of certain events occurring during the surgery, and may recall some or all of the events. Further, if the medication to relieve pain fails or is inadequate, the patient may feel pain while awake.

 Finally, cases involving general anesthesia often require the patient to be given medication intended to prevent movement. In very rare instances, the sleep and pain medications fail while the paralytic agent does not, making it virtually impossible for the patient to communicate this dire situation to the anesthesia providers.

My Story with Sleep Paralysis

I used to have this problem when I was in my early teenage and as much as I remember it was somewhere near class sixth or seventh. At some nights I used to wake up just after 10 mins of sleep and find my self motionless and till the time I got the control back on me, I would be badly breathing, puzzled and haunted.

But, this time it was different! I was returning back to my home town by road from Faizabad and was sleeping next to the driver seat with seatbelts on. Suddenly, I woke up and I was in the worst state of paralysis only my right leg could move about an inch. As the window of car was open, dust from the road was directly going in my mouth and I was still unable to close my own mouth. But, the brain was active and decided to hit my left leg with right and some how after struggling for over more than 15 minutes I slowly got the control back on my body. I will like shouting Wake Up, Wake Up to all my body parts.
Each time it happens, exactly one body part remains in the voluntary control of my mind and helps to wake up other parts of the body. ( Once it was the lower jaw).

Lastly, towards the end of this surgery, I completely felt exactly only  the last two stitches even though I was under local anesthesia.

When I told about this to my parents at that time, may be they thought that I was trying to draw attention or boasting or whatever but was never heard seriously. Yesterday, one of my friend told me the term and I was shocked that yes, I know this and I have been though this condition.


Lucid Dreaming : A lucid dream is any dream during which the dreamer is aware that they are dreaming. During lucid dreaming, the dreamer may be able to exert some degree of control over the dream characters, narrative, and environment. [Wiki]

"I sleep too much." - Everyone tells me this.

While introspection, I found out that I am expert Lucid Dreamer and just to extent the pleasure of dreams I extend my sleep durations . The only target is to complete that particular thought sequence. I can even resume my dream after a 10 minutes break.

Are these 3 things connected? A question that will now always haunt me.
And the non scientific hypothesis about demons etc. can never win my trust. So what exactly is it???

Random Numbers

Random Numbers

Anyone who considers arithmetical methods of producing random digits is, of course, in a state of sin.  -John Von Neumann, 1951


A random number is a number generated by a process, whose outcome is unpredictable, and which cannot be subsequentially reliably reproduced. This definition works fine provided that one has some kind of a black box – such a black box is usually called a random number generator – that fulfills this task.

However, if one were to be given a number, it is simply impossible to verify whether it was produced by a random number generator or not. In order to study the randomness of the output of such a generator, it is hence absolutely essential to consider sequences of numbers.

Random Number Generator

A random-number generator is a computational or physical device designed to generate a sequence of numbers or symbols that can not be reasonably predicted better than by a random chance.

Various applications of randomness have led to the development of several different methods for generating random data, of which some have existed since ancient times, among their ranks are well known "classic" examples, including the rolling of dice, coin flipping as well as countless other techniques. Because of the mechanical nature of these techniques, generating large numbers of sufficiently random numbers (important in statistics) required a lot of work and/or time. Thus, results would sometimes be collected and distributed as random number tables. 
Nowadays, after the advent of computational random-number generators, a growing number of government-run lotteries and lottery games have started using RNGs instead of more traditional drawing methods. RNGs are also used to determine the odds of modern slot machines.

Several computational methods for random-number generation exist. Many fall short of the goal of true randomness, although they may meet, with varying success, some of the statistical tests for randomness intended to measure how unpredictable their results are (that is, to what degree their patterns are discernible). However, carefully designed cryptographically secure computationally based methods of generating random numbers also exist, such as those based on the Yarrow algorithm, the Fortuna (PRNG), and others.
