"Aye, age old in this warfare,
the eternal struggle between darkness and light.
Fiercely is it fought all through the ages,
using strange powers hidden to man.
Adepts has there been filled with the blackness,
struggling always against the light;
but others there are who, filled with brightness,
have ever conquered the darkness of night.
Where e'er ye may be in all ages and plane,
surely, ye shall know of the battle with night.
Long ages ago,
The SUNS of the Morning
descending, found the world filled with night,
there in that past, began the struggle,
the age old Battle Darkness & Light."

"The prophecy of Shambhala states that each of its kings will rule for 100 years. There will be 32 in all, and as their reigns pass, conditions in the outside world will deteriorate. Men will become more warlike and pursue power for its own sake, and an ideology of materialism will spread over the earth. When the "barbarians" who follow this ideology are united under an evil king and think there is nothing left to conquer, the mists will lift to reveal the icy mountains of Shambhala. The barbarians will attack Shambhala with a huge army equipped with terrible weapons. Then the 32nd king of Shambhala, Rudra Cakrin, will lead a mighty host against the invaders.
In a last great battle, the evil king and his followers will be destroyed. By definition Shambhala is hidden."

"The battle of Armageddon refers to the final war between human governments and God. These governments and their supporters oppose God even now by refusing to submit to his rulership. (Psalm 2:2) The battle of Armageddon will bring human rulership to an end.—Daniel 2:44.
The word “Armageddon” occurs only once in the Bible, at Revelation 16:16. Prophetically, Revelation shows that at “the place that is called in Hebrew Armageddon,” “the kings of the entire inhabited earth” will be gathered “together to the war of the great day of God the Almighty.”—Revelation 16:14.
Who will fight at Armageddon? Jesus Christ will lead a heavenly army to victory over God’s enemies. (Revelation 19:11-16, 19-21) These enemies include those who oppose God’s authority and who treat God with contempt.—Ezekiel 39:7."

"The Mahdi will be only such a just ruler who will rule towards the end of the world and he will be one of Jesus’ aides.
It is noteworthy that Muslims believe that a Jewish messiah will emerge towards the end of the world. Nevertheless, they believe that he is not the Christ but rather the Antichrist who will be killed by Jesus upon his descent."
