A word(sentence)(heart) uses its person(mind).So one should have mind discipline. Mind discipline comes only through writing or typing those word/sentence by hand AGAIN after listening/reading those word/s. That means NOTES TAKING atleast once IS COMPULSORY FOR LEARNING/KNOWING/READING SUBJECT(or its chapter). Mere by-hearing doesn't give marks. Only analytical (why-what-how-where) thinking gives truthful knowledge about subject/topic for answering questions in future. Students must learn way of studies in academic world.

మాట (ఆలోచన ) అనేది విన్న/చదివిన  తరువాత దానిని ఫిక్స్ చేయటానికి రెండు సార్లు అడగాలి .
