A short discussion with mathematical calculations of the yugas or ages will explain the fact that the present age for the world is Dwapara Yuga, and that 194 years of the Yuga have now (A.D. 1894) passed away, bringing a rapid developn1ent in man's knowledge.

We learn from Oriental astronomy that moons revolve around their pla11ets, and planets turning on their axes revolve with their moons round the sun; and the sun, with its planets ancl their moons, takes some star for its dual and revolves round it in about 24,000 years of our earth-a celestial phenomenon which causes the backward movement of the equinoctial points around the zodiac. The sun also has another 1110- tion by which it revolves round a grand cen.ter called Vishnunabhi, which is the seat of the creative power, Brah,ma, the universal magnetism. Brah"fna regulates dharma, the mental virtue of the internal world.

When the sun in its revolutio11 round its dual co1nes to the place nearest to this grand center, the seat of Brahnia (an event which takes place when the Autun1nal Equinox comes to the first point of Aries), dharrna, the 1nental virtue, becomes so much developed that man can easily comprehend all, even the 1nysteries of Spirit.

The Autumnal Equir1ox will be falling, at the beginning of the twentieth century, among the fixed stars of the Virgo constellation, and in the early part of the Ascending Dwapara Yuga.* After 12,000 years, wher1 the sun goes to the place in its orbit which is farthest fro1n Brahma, the grand center (an even.t which takes place when the Autumnal Equinox is on the first point of Libra), dharrna, the mental virtue, co1nes to such a reduced state that rnan cannot grasp anything beyond the gross material creation. Again, in the same manner, whe11 the sun i11 its course of revolution begins to advance toward the place nearest to the grand center, dharma, the mental virtue, begins to develop; this growth is gradually co1npleted i11 another 12,000 years.

Each of these periods of 12,000 years brings a complete change, both externally in the material world, and internally in the intellectual or electric world, and is called one of the Daiva Yugas or Electric Cou pie. Thus, in a period of 24,000 years, the sun completes the revolution around its dual and finishes one electric cycle consisting of 12,000 years in ar1 ascending arc and 12,000 years in a descer1ding arc~ Development of dharma, the mental virtue, is but gradual and is divided into four different stages in a period of 12,000 years. The time of 1200 years during wl1ich the sun passes through a 1120th portion. of its orbit (see Diagram) is called Kali Yuga. Dharrnaj the mental virtue, is then in its first stage and is only a quarter developed; the human intellect cannot co1nprehend anything beyoncl the gross material of this ever-changing creation, the extern.al world.

The period of 2400 years during which the sun passes throt1gh tl1e 2120th portion of its orbit is called Dwapara Yuga. Dharma, the rnental virtue, is then. in the second stage of development and is but half complete; the human intellect can then comprehend the fine matters or electricities and their attributes which are the creatir1g principles of the external world.

The period of 3600 years during which the sun passes through the 3120th part of its orbit is called .-rreta Yuga .. IJharma, the mental virtue, is then in the third stage; the human intellect becomes able to comprehend the divine magnetisn-i, the source of all electrical forces on which the creation depends for its existence. rrhe period of 4800 years during which the sun passes through the remaining 4120th portion of its orbit is called Satya Yuga .. Dharrna, the n1-ental virtue, is then in its four th stage and corr1 pletes its full developn1ent; the hun1an intellect can cornprehend all, even God the Spirit beyor1d th.is visible world.
