So here friends the first trick :

Remember just           "L    B    S    K"

Confused what's this???

L = Lumbini, birh place of BUDDHA

B= Bodhgaya ,where he got enlighted

S = Sarnath, where he gave preachings

K=Khushinagar, where he died.

A man born----get enlighted---gave teachings---then died.
