There are certain things in or around us that are always found in specific numbers. For example, the number of sense organs in our body is five and the chakras in our body are believed to be seven. It takes 365 days to make a year and 24 hours make a day. In history, numbers appear as dates marking important events; in geography, they come as latitudes, longitudes, heights, and depths to mark locations on Earth. In mathematics, they measure quantities and give a meaning to concepts such as distance and dimension. In science, they define properties of substances. For example, the number of electrons in an element make it distinct, or the pH of a substance, which is again a number, defines whether it's acidic or basic. Numbers are a part of tradition, religion, and mythology too.
Almost every instant, we encounter them; in counting, measuring, judging, analyzing, and in many other things we do daily, we are dealing with numbers. They are with us throughout life. Some repeat; some, we never meet. Frequently coming across the same number or a particular numeric pattern is only a coincidence, you may think.
