Even the four ages of the Hindu chronology contain a far more philosophical idea than appears on the surface. It defines them according to both the psychological or mental and the physical states of man during their period. Crita-yug, the golden age, the “age of joy,” or spiritual innocence of man; Treta-yug, the age of silver, or that of fire--the period of supremacy of man and of giants and of the sons of God; Dwapara-yug, the age of bronze--a mixture already of purity and impurity (spirit and matter), the age of doubt; and at last our own, the Kali-yug, or age of iron, of darkness, misery, and sorrow. In this age, Vishnu had to incarnate himself in Christna, in order to save humanity from the goddess Kali, consort of Siva, the all-annihilating--the goddess of death, destruction, and human misery. Kali is the best emblem to represent the “fall of man;” the falling of spirit into the degradation of matter, with all its terrific results. We have to rid ourselves of Kali before we can ever reach “Moksha,” or Nirvana, the abode of blessed Peace and Spirit. With the Buddhists the last incarnation is the fifth. When Maitree-Buddha comes, then our present world will be destroyed; and a new and a better one will replace it. The four arms of every Hindu Deity are the emblems of the four preceding manifestations of our earth from its invisible state, while its head typifies the fifth and last _Kalki_-Avatar, when this would be destroyed, and the power of Budh--Wisdom (with the Hindus, of Brahma), will be again called into requisition to manifest itself--as a _Logos_--to create the future world. In this diagram, the male gods typify Spirit in its deific attributes, while their female counterparts--the _Sakti_, represent the active energies of these attributes. The _Durga_ (active virtue), is a subtile, invisible force, which answers to Shekinah--the garment of En-Soph. She is the Sakti through which the passive “Eternal” calls forth the visible universe from its first ideal conception. Every one of the three personages of the exoteric Trimurti are shown as using their _Sakti_ as a _Vehan_ (vehicle). Each of them is for the time being the form which sits upon the mysterious wagon of Ezekiel.
