If we look back in the history, many of the disaster have occurred because of the misuse of science. Science is powerful but the same science can be dangerous if put in the hands of ignorant. Atomic bombings, nuclear disasters, cyber war-fare, biological weapons such as Anthrax are some of the examples of the misuse of science. Science works with solid evidences and empirical facts. If something is out of our senses and mind, we usually label that as illogical or abnormal. Vedas were discovered by extra sensory faculties of Rishis. Some examples of extra sensory faculties are clairvoyance, clairaudience, levitating effects defying gravity, mentally controlling physical objects (ancient Vedic Vimanas could also be mentally controlled by bringing coherent thoughts pattern) etc. There are realities that normal human senses cannot register to our brain. For example, infrared wave, ultra-wave etc. Our eyes cannot even see the movement of air! How can we rely on such senses which doesn't even let us see the air? Plus, this senses are registering illusory sensation; for example, blueness of the sky. Blueness of the sky is just an appearance because blue light reach faster to our eyes. If we tilt the axis of our earth such that green light reach faster than the sky would appear green all the time! Science has its limitation because it relies on these faulty senses and limited mind. We cannot put the whole universe in a laboratory and explain the cause of this universe. Therefore, some other technique is required. Rishis went beyond their senses and mind and understood the reality as it is. What is sound? You will understand sound only when you hear it. What is sight? You will understand sight only when you see things. Similarly, to understand Vedas, you must experience the subtle realities of the Vedas! When you realize that Vedic mantras really do work, then you will understand Vedas. Otherwise, trying to explain Vedas to someone who gets excited by seeing a naked lady is like trying to empty the ocean drop by drop. Wise people will never do that. There are certain qualifications which lets student fit to understand Vedas. One such qualification is self-control. Can you control your desires? If yes, you are fit to study Vedas!
