It is advised herein that the bore in the copper measuring pot must be made with a probe weighing not more than four masa and measuring not longer than four fingers. This regulates the diameter of the hole. The pot is submerged in water, and the overflooding time is called a danda. This is another way of measuring the duration of a danda, just as time is measured by sand in a glass. It appears that in the days of Vedic civilization there was no dearth of knowledge in physics, chemistry or higher mathematics. Measurements were calculated in different ways, as simply as could be done.
