RISHI LITERATURE AND MATHEMATICAL CALCULATION OF TIME http://www.shriramsharma.com/india's_future_is_bright_an_emerging_super_power.htm
WHY SHOULD THIS VERY HOUR BE LABELLED THAT OF ERA JUNCTION?
With reference to mathematical calculation of time the word ‘Yuga’ or era is utilized in many ways. In those days when particular trend is in vogue it is called in that particular manner. Examples are Rishi Era, Colonial Era and People’s Era. The all round progress, peace and apt management in the days of Ramrajya or Ram’s Rule was well renowned as Satyuga or Golden Era. A struggle oriented aspect of Krishna’s humungous India Rebuilding Program was termed Mahabharat. During King Parikshit’s time Kaliyuga or Dark Age manifested and a description is given in Puran or Indian mythology regarding the king’s utterances. Even today we talk of Computer age, Robot Age and Scientific Age. Many authors conjoin the word Yuga to their writings. As an example is Yashpal Jain’s ‘Yuga Bodha’. Over here the word Yuga means period in time. It means a time period that is noteworthy or an era which connotes a Yuga.
The calculations of eras are carried out in many ways. Amongst these are calculations for 1000 years. Generally the atmosphere changes every 1000 years and noteworthy changes are seen in various traditions. The end of 20th century and commencement of the 21st century is looked upon as end of one era and sacred commencement of a new era.
In the same way in Panchangs or almanacs there are discussions of so many beliefs related to commencement of Samvatsars. According to one school of thought an era spans over millions of years. On this basis we can say that billions of years have lapsed by ever since human civilization commenced and that it will take more than thousands of years for the current Kaliyuga or Dark Age to end. Yet based on available records historians opine that human evolution is not greater than 1.9 million years and this has been further proved using modern scientific technology.
At the time of calculating time negation is generally due to a flaw in its presentation. In that era calculation mentioned in various texts by partitioning the time of revolution of the sun into 4 major parts 4 Deva Yugas have been envisaged. One Deva Yuga is said to be of 432,000 years. On this basis a description of the end of Kaliyuga or Dark Age mentioned in religious texts very much correlates to the present times.
It is highly possible that under such conditions of contradictions people may not easily have faith in this mathematical calculation of time hence over here we will say that the word ‘Yuga’ means that period of
