The Yugas And The Avatar
"In this context, I shall tell you today the inner meaning of the different Yugas — Treta Yuga, the Dwapara Yuga and the present Yuga.
In the Treta Yuga, the divine elements were on one side and the demonical elements were on the other. At the time of the Rama Avatar, the divine elements were in Ayodhya and K-ishkinda and demonic forces were in Dandakaranya. The two elements were in separate regions. Rama waged war against the Raakshasas (demons) in Dandakaaranya (forest) and protected the Rishis (sages). This is the inner meaning of the Rama Avatar in Treta Yuga.
In the Dwapara Yuga, the divine and demoniac elements, namely, the Pandavas and Kauravas, were in the same kingdom. In such a situation. Krishna gave his army to the Kauravas, and without wielding any weapon himself, gave his support to the Pandavas in the great battle of Kurukshetra. He used others as instruments.
But today, these divine and demoniac forces are battling in each human being. This is the mark of the Kali age. In Treta Yuga, Rama fought the battle in person. In Dwapara Yuga, Krishna played the role of a witness, using others as His instruments. He did not engage in the battle himself. In the Kali Yuga, because the two opposing forces are inside each individual, the Lord plays the role of a witness and as the conscience. Man has to use the power of discrimination given to him to fight evil forces within him. He has to foster the divine elements in him by his own efforts and listening to the voice of his conscience. The freedom to choose has been given to man for this purpose. The freedom is to be used to discriminate between right and wrong, good and evil and to foster divine qualities. This is the unique feature of the Kali age. In this age, each individual has to fight against the demonic forces himself and vanquish them. When this is accomplished, man's inherent divine nature will manifest itself of its own accord." Sai Baba, SS, 1987, p. 183
Kali Yuga Or Kalaha Yuga
"Of the four Yugas - Krita, Treta, Dwapara and Kali - the present Yuga is called Kai Yuga. In truth, it is 'Kalaha Yuga', the Age of Discord. There is discord everywhere —between husband and wife, between preceptor and pupil, and in every other relationship. What is the reason for this discord? The absence of mutual trust. No one trusts another. As a result, hatred and bitterness are growing in the social, ethical, political, and economic and every other field. There is discord in the scientific field. The lack of trust has blinded people towards each other." Sai Baba, SS, 4/93. p. 87
