"Whenever there is decay of righteousness... and there is exaltation of unrighteousness,
then I Myself come forth... for the destruction of evil-doers, for the sake of firmly establishing
righteousness, I am born from age to age." --- KRISHNA- Bhagavad Gita- fourth discourse
Hindus are awaiting the coming of the Kalki Avatar at the end of this present age, Kalki Yuga (Dark or Iron Age). Baha'is believe that the Kalki Yuga age has already ended and, as promised in the Bhagavad Gita, the Lord has again manifested Himself to humanity.... this time with the name Baha'u'llah. Baha'u'llah is the Kalki Avatar.
Baha'u'llah's name means the Glory of Bhagwan or the Splendor of Ishvara. The coming of Baha'u'llah is therefore the start of the Sat or Krta Yuga (Golden Age). It is the time when people will return to righteousness and the world will be at peace.
