Some great lines... from the holy sire

1) maaya maanusha yaovvana garvam
harathi nimisha kaalaa sarvam
(Sanskrit) - Aadi Sankaracharya Swami

(The pride associated with your youth is only a mirage. It eats away minute by minute and with that your whole time)

2) Chitram vatatarormooleh
Vriddhaat sishyaan gururyuvaan
Gurostumounam vyaakhyaanam
Sishyaastu chinnasamshayaat
(Sanskrit)- Aadi Sankaracharya Swami

(Aha! what a strange thing! Under the banyan tree are sitting the teacher who is in his tender age and his disciples who are all frail, senile persons. The teacher is all silence; yet he is able to obliterate all their doubts)
