I agree with the others, don't treat bigeminy. ...It's some kind of EMS lore that never seems to die that bigeminy is a terribly malignant rhythm and has to be squashed no matter what the consequences.
The meaning of the autumn equinox is intertwined with that of the four points of the year (the two solstices, and the spring equinox), which each mark stages in the esoteric work that begin anew each year, and form a symbolic cross in the wheel of the year, with the sun (Son/Christ) at the center.
The autumn equinox is a mysterious time. It marks an essential passage in the process of enlightenment that is often overlooked, misunderstood, and mistaken as dark and heretical. It is the time of balance between day and night, before night takes over and brings the coming winter, a time of darkness and death.
