SIMPLE MEMORY TECHNIQUE: How the mind learns anything, how to understand and memorize anything easily

Why do they say that they have a clear understanding of a particular subject or topic?
That they have memorized something.....
These questions ultimately lead us to the most popularly spelled word, "concentration".

                   Actually,  the mind thinks in images. When we become able to draw a clear image of some facts in mind, we become able to understand those facts and then these are memorized.

Many great scientists like Edison, Einstein etc. had difficulty in learning some subjects in their childhood.
They really lacked sharp memory???????????
certainly not.....

💡Actually, when we read something we begin to think about that,  when we think and draw the facts in mind, visualize them, we begin to understand gradually. Now we have successfully memorized these things.
This fast learning or long term learning comes from a deep interest in a particular field.

  Have you ever noticed the academically weakest student of the class(that may be anyone, you or me), when goes to watch his favourite movie or read his most desired novel---------he does not forget even the single character including the dialogues.

Interest and imagination integrated with proper training and with proper use of time play a vital role in the making of sharp memory.
