What is the meaning of fancy word named code optimization(explained with Buddha principle)

I actually heard this talk from sukisivam and I thought of associating it with topic called code optimization.I think everyone have heard about Buddha.If not google it . Now let’s get into the discussion .The discussion is as follows “once a man asked Buddha guruji everybody telling that you have attained something great.Could you tell me what you have actually attained for that Buddha told that “I have not actually attained anything rather I actually left the unnecessary things which are minimum to retain the supreme thing”. Do you know why the word retain is used instead of attained since it is there with us but the junk seems to be dominating it which has be to be filtered or cleaned in order to retain the information( like data mining) This word has much more powerful meaning than you think. This principle not only applied to programming it can be applicable to various scenarios(example in case of database normalized database is the best one).I am pointing to a specific scenario here called programming.This is the principle that every programmer wishes to attain it.Everybody can do a program.But it doesn’t mean that it is efficient and readable one.Only a few can achieve it in action by applying the Buddha principle.
