i havent told anything as good or bad.
there are 4 books in our religion called vedas. composed over 3500years ago. the people didnt have any script that time in our country. the whole books went on for ages through hearing. u would object that there must be mistakes in those. but when we find the same words, same phrases & same sequence in the same book over a whole country (7th largest) which totally have different cultures in various parts we have toadmit their memories & concentration power.
one of the most imporatnt reasons of people's concentration stated in the vedas is celibacy.
sacrificing pleasures & control on ourselves can give us patience, tolerance, concentration.
if u say i am claiming something impossible all i can say is i am a girl of 19 has been able to memorise a lot of scriptures of our culture of the language i dont understand.
we didnt have mnemonic science at that time, atleast no proof of mnemonic science existing in india.
god bless u.
