(Please note that I only use the sidereal zodiac in my work, so the charts and predictions I share on my blog are based on the sidereal zodiac, Lahiri ayanamsa).
In most of 2019 and the beginning of 2020, Pluto and Saturn conjoin Ketu, the Moon’s South Node, in the sign of sidereal Sagittarius. The Sun, Moon, Jupiter, Mercury, and Venus will join this Sagittarius conjunction at various times forming a significant stellium in Sagittarius (three or more planets in one sign). Rahu, the Moon’s North Node, will transit at the same time in sidereal Gemini. Therefore, the harbingers of change known as eclipses (which occur when the lunar nodes line up with the Sun and Moon every six months) will occur in the Sagittarius-Gemini axis beginning in early January 2019; and, this pattern will continue through 2019 and much of 2020.
Some of the general themes of the Sagittarius-Gemini sign axis revolve around cosmic law and right action (dharma); educational institutions, knowledge, and ethics; logic and faith; philosophical ideals and principles; innovative developments in communication, learning, technology, banking, and currencies; the search for freedom and justice; and the polarity between diversity and unity.
