The sign of Gemini by mode and element (Mutable Air):

The sign of Gemini, symbolised by the Twins, has a Mutable quality (along with Virgo, Sagittarius and Pisces). The Mutable modality signifies the end of the seasons, when the weather is more in flux. The Mutable energy represents flexibility, versatility and
changeability.

Gemini is one of the signs (along with Libra and Aquarius) which is also associated with the Air element concerning the rational mind, sharing ideas, knowledge, communication, logic and speech. Some keywords for Gemini include: intellectual, networking, quick-witted and adaptable. Geminis may be avid talkers, have strong mental abilities and enjoy social interactions with others. They are often curious, like collecting many pieces of information and generally know lots of things about lots of things!

Gemini’s ruling planet: Mercury

Gemini is ruled by the planet Mercury. Mercury is associated with education, communication, speech, language, writing, connecting with others, debating, siblings, being light-hearted and intelligent. Mercury can also distract and make communications de-stabilised.

The sign of Sagittarius by mode and element (Mutable Fire):

Sagittarius also has a Mutable quality or mode. With Sagittarius, imagine the need to be on the move in some way, either physically or mentally. Sagittarius is also one of the signs (along with Aries and Leo) which is associated with the Fire Element concerning enthusiasm, inspiration, warmth, passion and intuition. Some keywords for Sagittarius include: adventurous, freedom-loving, philosophical, outgoing and restless. It can also represent being exuberant, open-minded, having an interest in higher learning, being visionary and exploratory,  seeking meaning, growth and improvement, focussing on the future and broadening horizons through journeys.

Sagittarius’ ruling planet: Jupiter

Sagittarius is ruled by the planet Jupiter. Jupiter represents faith, trust, opportunity, abundance, luck, confidence, courage, wisdom, our quest for meaning and generosity. The need for expansion can however lead to excess, exaggeration, over-indulgence and risk-
taking, and the possibility of falling prey to illusions and squandering resources.

Full Moon aspects:

The Sun gives us inspiration to move towards a goal when in Sagittarius, however, with the Moon in Gemini, we may be unfocussed and even scattered in our decision to achieve any targets we have set for ourselves. Examining all options, making clear decisions and staying focussed can be difficult at this time. Some potentialities and possibilities may fall by the wayside or go on the back burner to be explored another day. We might change our minds about a decision which is preferential to continuing on a path not meant for us.

Venus and Mars in Sagittarius, Sun and Moon square the Nodal Axis

Venus and Mars are co-present with the Sun in the sign of Sagittarius, while the Sun and the Moon are at the ‘bending of the Nodes’ meaning they are both 90 degrees away from the Nodal Axis in Pisces (North Node (dragon’s head) – where you’re going) and Virgo (South Node (dragon’s tail) – where you’ve been). The Sun is at the Southern Bending, and therefore connected to the South Node, being 90 degrees away from the North Node in a clockwise direction. Conversely, if the Sun is 270 degrees away from the North Node, then it is at the North bending and connected with the North Node.

We are starting to get in touch with any spiritual meaning or our beliefs (Pisces), and getting out of our own way, being adaptable with our work, health, service and daily routines and attachments (Virgo) that are holding us back. Are you unhappy with any of these areas in your life? If so, this is a sign we need to be more flexible, move out of our ruts and move more into alignment with our values (Venus) and soul purpose. Maybe ask yourself, what does our soul want (Pisces)? What is the vision (Jupiter)? Plus, in what practical form do we need to express this (Virgo) in order to go after (Mars) and create what we want? This is Mutable energy, so making any change, no matter how small the adjustment is, will assist in re-directing your vision and ultimately your life in a more rewarding direction.
