Vernal equinox

In astronomy, equinox can have two meanings:The moment when the Sun is positioned directly over the Earth's equator and, by extension, the apparent position of the Sun at that moment - see below.A moment in time at which the vernal point, celestial equator, and other such elements are taken to be used in the definition of a celestial coordinate system - see Equinox (celestial coordinates)

Seasons The seasons are at least in part due to the inclination of the earth's axis, and wholly according to this explanation in modern astronomy. If there were no inclination -- if the ecliptic coincided with the equator, and the earth's axis with the poles of the equator -- there would be no seasons. In satya yuga there were no changes of season, but an eternal spring which lasted as long as the lack of polar inclination endured, but which came to an end when the third root-race fell into "sin" -- the two events coinciding. The earth's axis when without inclination is at right angles with the plane of the ecliptic. The titans or kabiri are described in The Secret Doctrine as the generators and regulators of the seasons, thus showing that they take their part with the karmic lipikas in the cosmic history of the globe. Spring, summer, autumn, and winter correspond with other quaternaries, such as the four points of the compass and the four elements; and also represent a cycle of changes from birth to dissolution and rebirth.
In theosophical literature the earth's axis is said to undergo a secular movement of inclination with interims of pausings and smaller changes, or what may be called librations; and this secular movement is on the whole continuous, so that in course of long ages the axis of the earth becomes inverted, and consequently the poles are reversed; continuing their movement, they finally return to the position of right angularity with the plane of the ecliptic.
