End of Kali Yuga
A Visitor: Does Kali Yuga [Iron Age] still continue?
Sai: Yes.
Visitor: Because in America several books say Kali Yuga has ended and another is in force.
Sai: No. Before the Kali Yuga ends, there is a space in between. The situation is similar to the motion of a fan. When the fan is switched on there is an interval before it picks up speed, and when the switch is turned off, the fan continues to run for a time. The world is also turning round like the fan. Even if the Kali Yuga stops, it still has a few more revolutions to go before the final ending.
The situation is somewhat as found with a string of light poles. There is a distance of about a furlong between each pole. The light from a pole extends about half way to the next pole and at some point the light of the next pole is seen faintly there itself. There are four yugas. The sequence is circular, and when the last is finished, the whole cycle starts all over again. Kali Yuga still has 5,320 years before ending.
A Visitor: How does Kali Yuga fit into the astrological signs?
Sai: The predictions made in astrology are somewhat different from each other in their readings, and this implies some error. It is difficult to pinpoint time factors precisely, and this leads to errors. Astrology is able to view the stars from only one angle of vision; the stars are not seen totally, and this is a source of error. Everything changes. People change and so also do the stars. Astrologers do not take these changes into account and this is a source of error. Astrologers do not know their science perfectly and this leads to errors. Astrologers are not living lives of great purity, and for this reason spiritual help is not fully within their reach, and this leads to errors. With all these errors, astrology cannot be relied on and it is not worth bothering with.
