From the time man stepped on the canvas of world history, space-time has been shrinking continuously. Today, in the silicon and micro-processor age, the speed has picked up even more rapidly. For most people who have dedicated their lives in the pursuit of material knowledge and wealth with dedication and passion, there comes a time when they find their system overloaded with information.
Sensory overload from the ever changing outside world creates a crisis, in the pause of the moment one asks; is there anything else beyond the material reference frame that is relatively more stable and permanent? This is not a new question for the human race. Long, long time ago in the Indus-Saraswati valley, a very small group of people (Rishis) asked the same question and came up with answers. They put forth their answers in a very logical and systematic way in the Vedas.
