Today, Fathers' Day is shared with the Summer Solstice, the longest day of the year.
The word, Solstice, itself, refers not only to the points where the sun is its greatest distance from the earth's equator, but also to a turning point or a culminating point.
In the Northern Hemisphere, the days will begin to get shorter, but the "dog days of summer" are just beginning.
I'm not sure of the micro/macro cosmic significance that the Solstice and Fathers' Day coincide this year. But perhaps it is just a reminder to balance the masculine and feminine energies as they circulate in this turbulent world. Perhaps it is a reminder that with every hour of light, there is an equal hour of darkness and those hours play out within the span of a year.
Likewise, with every hour of darkness, there is an hour of light.
