The science of memory

'When you are deluded, every statement is an ulcer; when you're enlightened, every word is wisdom.'
Zen proverb

Life is a great journey which all of us must traverse. We form impressions of the world from the time that we are born till the time we die. These impressions are stored as different memory traces in our brains in different forms. Some of these are unformed visual memories from the time we were babies, some are photographic explicitly vivid memories, some are auditory memories, others of odor, touch or other senses. We meet myriad people along the way, have a panoply of experiences and forget 99.9% of them. Possibly this is an evolutionary mechanism that helps mankind to move on and not get stuck in the past. However, imagine if you could remember people, names, information, numbers and much more. How much efficient and powerful you could be! After all knowledge is power.
If you plod along life without a systematic plan to utilize your memory networks, you will expend a great deal of effort more than an individual who has a systematic method of memorization.
