It must also be remembered that the turning of our tiny systemic wheel, and the revolution of a cosmic wheel can be hastened, or retarded, by influences emanating from unknown or unrealized constellations whose association with a systemic or a cosmic Logos is as mysterious relatively as the effect individuals have upon each other in the human family. This effect is hidden in logoic karma and is beyond the ken of man. 12 Man must understand the nature of the wheel in which he is turned, called in Sanskrit the wheel of Samsara. This latter word derived from the root Sru, to move, indicates a motion wheel or the great wheel of changing life in which the human entities have been called upon to work and which must never be abandoned out of compassion for man and in obedience to the law of oneness which connects the many, in the opinion of all true yogis and Shri Krishna. The Teacher gives the nature of the samsaric wheel in a certain peculiar way which deserves to be thought over by you all.
Rain comes out of yagna and yagna out of Karma.
Karma is out of the Veda and Veda is of the Eternal. If we divide this seven according to the theosophical plane of a lower four dominated over by a higher triad, we get form, food, rain and yagna as the lower four and karma, Veda and eternal substance as the higher triad. The eternal substance that pervades all space, worked on by the world song and giving rise to all the laws of karma that govern the development of the world, develops a lower four and this four is started by yagna - the spirit of evolution that connects the higher and lower or in Puranic fashion, the spirit that seeks to add to the harmony of the unmanifested by giving it a field of disharmony to work upon and establish its own greatness. This spirit of yagna in its way to produce the manifested form gives rise to the Parjanya or rain. The word Parjanya is applied to rain and often times to a spirit whose function is to produce rain.
