Can we believe our senses?

What ever we perceive about the outside world is is due to the input from our five main sensory organs.Every moment of our lives we are bombarded with tons of sensory information  from these senses. Our brain seems to be doing a fantastic job in decoding all these information and taking the right decision..But is it really the case..?  
When we get up in the morning and look at the outside world we feel that what we are seeing is the world as it really is..But illusion teaches us that it is not really the case.. In-fact we see illusion because of the brains ability to make sense from the insensible. But the illusion disappearing ball illusion arises from the fact that our brain tends to predict the future from things that have occurred in the past. By doing this the brain does save a lot of time.Otherwise if the brain would have to decode all the information from the visual information alone then we would have to grow huge brains..In-fact how much we love colors there is no thing as colors..its just the creation of our brain to make things appear beautiful and sensible before us..It is not only the eyes that can be fooled but other senses too..for example when we eat a chips we feel that it is crunchy because of the sound we hear after biting it..If it is so designed that we eat a chip and hear a low frequency sound at the same time we will feel that the chips is less crunchy.here are some examples to fool our senses of touch and hearing.....So we see that we cannot believe really our senses..But it is good for our survival and also makes the life whole lot entertaining...!! :-)

What is reality and what is illusion?

Wikipedia defines reality as Reality is the state of things as they actually exist, rather than as they may appear or may be thought to be.But can reality be so easily defined?? Who defines and who knows what actually exists and what not..When I am writing this blog or you are reading it you are feeling like you are sitting or standing but actually we are zooming through space at amind boggling speed of 67,000 miles per hour. We feel that our body is solid but it is mostly empty spaces...Scientists first thought that the smallest particle that consisted reality was atom but this theory later seemed to be an illusion and the electrons, protons and neutrons were seemed as elementary. Now days this too seems illusion and it is said that there are 16 elementary particles..


But can this even be said as true reality??? Let me make myself clear...every science student knows about young's double slit experiment...In that appearance of multiple patterns of light on the screen is explained by the wave nature of light..but even when only single photons are fired through the slits multiple stripes still appears on screen...How can a single photon pass through single slit and both the slits at the same time is beyond the explanation of physics at present..It can only be explained by the theory of parallel universe and considering the world is a great holographic image of the things occurring at the boundary of our universe..So hindu philosophy has correctly termed the whole universe as maya...If there is only one truth in the universe it is our atman...perhaps....Or who knows perhaps this is also illusion..!!!
