Till his last breath flowed away from him he wanted to be known as a teacher not a scientist . He was giving a speech to the students in shillong before his death , this proves that he is a greater teacher than a scientist . He always wanted to be a teacher than a scientist.We can learn more from him that makes him a teacher and to say there are no words but only deeds by him that makes my mouth drop. sad that he is not present here.He encourages  every one to question thats what a teacher does.He teaches the nation to do the best from his deeds. he always loved teaching
till his last breath he taught to students
he talked to students and solved their doubts thats what a teacher does
he taught about life
are these enough
tell me plz
