We perceive this world through our five senses – sight, sound, touch, taste and smell. So our eyes, ears, skin, tongue and nose are the five receivers which help us make sense of the world around us.
Nature has designed each of our senses meticulously. In spite of that, if used individually, these five instruments are insufficient to help us function normally. That’s why for most of our routine activities we use combination of more than one sense organ. For example, walking requires use of eyes, skin and ear (for balancing), for communicating we use ears and tongue etc.
For most people who are passionate about learning, reading is a primary source of information. However, in reading you’re only using one instrument – eyes. These days, audio books is another popular and very effective medium to learn new things. In audio books (and podcasts), you’re again engaging only one sense – hearing.
In fact, for thousands of years, until the discovery of print medium, most human civilizations transferred their knowledge orally from one generation to other – their own version of audio books, if you will.
But what if you could engage both these senses together? Don’t you think the retention of what you learn would be much better?
