Great advice! Thanks for your input.
How to became strong in endgame!

Sure, but you didn't really say how.
How should I practice endgames? How do I learn the art of a given position?
How do I develop my endgame calculation power?

THERE ARE SO MANY COMMON THEMES IN END GAME POSITIONS
1) KING & PAWN END GAMES
2) KING & KNIGHT END GAMES
3) KING & ROOK END GAMES
ETC..,
END GAME SPECIALISTS CONSTRUCT CERTAIN PROBLEMS BASED ON THE ABOVE SAID THEMES...
WE MUST CAREFULLY STUDY THOSE THEMES IN ORDER TO MASTER ENDGAMES
IT SEEMS CAPABLANCA HAD BECOME A GREAT PLAYER WITH A GREAT KNOWLEDGE OF ENDGAME ALONE..............

That's completely incorrect. And why the caps?

How to become strong in endgames:
1) read books on endgames and learn critical positions and techniques: opposition, lucena position, philidor position, opposite coloured bishop drawing techniques, the list goes on
2) play lots of games and apply the knowledge you have learned
3) study the games of grand masters and try to understand why they make the moves they do in the endgame
There is no simple way to become strong in the endgame :) you need to study and practice, a lot.

I'd also add that setting up such critical positions to play against an engine can be good as well.

Good advice from Sagnikjyoti, not only for begginners but also for the advanced!
But it would be far better if you please notify how to practice and learn the endgame?!

I'm working my way through Mikhail Shereshevsky's "Endgame Strategy". This is is a pretty good read and emphasises strategy rather than a chapter on knight endgames followed by rook endgames etc which seems to be the format for the drier books out there. He has chapters on "exploiting two weaknesses", "centralising the king" , "two bishops" ...
This is a great book with only one thing that annoys me about endgame books: I like to see all the moves in a game, even if unannotated.(Chernev got this right with his Capablanca Best Chess Endings)

Playing a lot of blitz is good for most practical endgames it seems like... I usually outplay my opponent in endings when time is short.
"It's good practice because I win in these practice sessions" heh, great logic.
It should read, playing a lot of blitz is good for most practical endgames because I can outplay my opponents in endgames with long time controls...
but of course that's not true.
The endgame is the very important and vital course of Chess. To became stong in endgames the following steps should be followed:
(i) You should practice endings regularly. Not just memorising the position but knowing the art of the given position.
(ii)You should develop your calculation power in the endgames because it is just mathematics.
(iii)You shouldnot consume much time in any uncomplicated positions rather than you should save time for endgame.
