Into the future :The clouds are oozing with enormous thunderstorms ,wind is moving strongly and at the ground a man with a sword which is oozing with flames and lightning is fighting an creature(looks like a demon with an evil form) who is covered in flames,smoke and a mysterious power strikes.
BACK TO THE PAST(unknown timelines):
There is a god named "vishnu" who takes incarnations in the world at every yuga.
(yuga - it is a timeline ,there are 4 yugas according to ANCIENT texts,they are satya yuga , treta yuga, dwapara yuga, kali yuga[present yuga] ).
"when the evil rises in the world on every yuga and destroys the nature laws and starts killing inocent people".vishnu kills the evil energy in every yuga when they rise in the world with his incarnations . Till now Vishnu had taken total 9 incarnations and in those he has completed 8 incarnations life forms the main four incarnations were:
VARAHA(Boar form) AND NARASIMHA(Man-Lion form) -SATYA YUGA(first yuga).
RAMA(Man form)-TRETA YUGA(second yuga) .
KRISHNA(Supreme god form)-DWAPARA YUGA(third yuga).
Till now after killing the every evil on each yuga vishnu would complete his life form (returns) to his original form ,leaves the world and there is an also an incarnation who didnt completed the life form who is immortal and not appeared to the mankind after dwapara yuga(third yuga) ,the incarnation is:
PARASHURAMA(Warrior-Sage)- Born in TRETA YUGA(second yuga).
ALSO ACCORDING TO THE ANCIENT TEXTS AND PROPHECY VISHNU WILL TAKE INCARNATION IN "KALI YUGA(PRESENT TIMELINE-which is the 4th yuga) AS GOD KALKI WHO WILL KILL THE EVIL NAMED KALI WHO WILL DESTROY THE MANKIND IN THE KALI YUGA
