FULL MOON IN ARIES – We will have the energy and power to make necessary changes (October 20, 2021)

by Anne Reith, Ph.D.

AstrologyIn the Pacific Time Zone, the Moon will be full at 4:54 p.m. on Wednesday, October 20.  With this Full Moon, the Sun in Libra will be in opposition (180°) to the Moon in Aries.  To further clarify how this Full Moon will impact you on a personal level, locate 28° of Libra and 28° of Aries in your birth/natal chart.  The issues associated with those two houses are going to be most impacted by this Full Moon’s presence.

All Full Moons involve finding a better balance between the two signs involved.  This time, those signs are Libra and Aries:

  • The best qualities of Libra include being cooperative, harmonious, diplomatic, social, and patient. The lower expression can involve being indecisive, dependent, or pouting over perceived injustices.
  • The higher expression of Aries includes being independent, initiating, enthusiastic, direct, energetic, confident, and fun-loving. The lower expression can include being impulsive, competitive, or even aggressive.

Where Libra wants to make everyone happy, Aries wants to do its own things and not worry about others.  Neither end of this continuum is “wrong,” and each approach to life is appropriate at certain times.  This annual Aries Full Moon is when we are asked to evaluate whether one end of the continuum has been receiving more of our energy than the other.

However, as we have been discussing over the last few Moon Updates, Pluto is going to be playing an important role in our lives between now and March 2022.  For some, we may already be fairly familiar with its impact.  However, for others, this Aries Full Moon may be the first time the energy of Pluto will be making its presence known because it’s going to be hard to avoid during this lunar event.  Let me explain.

At the time of this Full Moon, the Sun will be conjunct (0°) Mars, which means that both the Sun and Mars are in opposition (180°) to the Moon.  Both the Sun/Mars in Libra and the Moon in Aries are squaring (90°) . . . you guessed it . . . Pluto in Capricorn.  This forms a right triangle shape, also known as a t-square planetary configuration.

The planets involved are located in Aries, Libra, and Capricorn, and these are all cardinal signs.  Therefore, this would be described as a cardinal t-square.  T-squares are tough because they require change; and cardinal t-squares don’t just require change, they demand that it be quick and dynamic.  Having Libra involved might normally soften the urgency a bit; however, with powerhouses Mars and Pluto both playing a role in this t-square, it may be difficult to hold any changes at bay.

Because all the other planets square Pluto, it is described as the “focal planet” in this cardinal t-square.  Pluto indicates the type of energy that will help us find a balance between the opposition (i.e., Sun/Mars & the Moon).  This planet may be a small in size, but it’s all about power, power, power.  It’s asking us make changes that actively (cardinal) transform and heal us (Pluto).  This may mean that secrets will be revealed about others or that we need to unearth truths within ourselves . . . or both!

How can be we best navigate this?

  • First, we need to monitor our energy levels because this dynamic t-square involves both Mars (energy) and Pluto (power). If energy begins to build up too much, this could cause us to make impulsive decisions and/or feel angry, agitated, tense, and/or frustrated.  Effective ways to vent the energy should focus on activities that use our muscles and preferably activate our cardiovascular system.
  • Second, we need to do our best to make sure we are using our personal power to make any changes. We need to avoid using the lower expression of Pluto, which would be force changes to occur.  I think we can all agree that forcing changes on ourselves or on others never goes well.  If in doubt about which approach you are using, look for signs that we are using force rather than power.  This may include compulsive behaviors (i.e., you feel you can’t stop yourself), knee-jerk reactions, and/or trying to control a situation or person.

So, what might be changing in our lives during the time of this Aries Full Moon?  If we have access to our natal chart, we can look to the houses involved.  However, regardless of the houses, there are other hints available to us:

  • The opposition that is involved in this cardinal t-square is the Full Moon between Aries and Libra. Therefore, the changes may involve needing to find a better balance between our independence (Aries) and our interdependence (Libra).  Support for this possibility is provided by an inconjunct (150°) between Venus and Uranus, which tells us that any changes (Uranus) may involve making adjustments (inconjunct) in our relationships (Venus).
  • Another hint may be the fact that Uranus is currently located in Taurus. Again, the inconjunct between Venus and Uranus may mean we have to make difficult choices (inconjunct) related to our possessions, our job/income, or our finances (Taurus).
  • Additionally, given Venus is involved through the inconjunct with Uranus and Venus is associated with both relationships and finances, this adds further support for tough choices that impact both of these areas.

Now, before you start freaking out, none of what I have described about this Aries Full Moon is meant to be “a bad thing.”  Yes, we will have to consciously choose to manage the incredible energy involved.  If we can do that, then whatever changes are made during this time are intended to help us transform and heal at a deep level (Pluto).  This may require letting go of whatever is no longer serving us, which can be challenging.  However like the phoenix rising from the ashes, we will be stronger through this process.  If we choose to resist or avoid this opportunity at a rebirth, then we will lose the chance to live a more authentic life . . . a life that is aligned with who we truly are meant to be.  Luckily, the involvement of Mars means we will have the energy and courage to do what is needed.

As usual, there is support provided for any changes and adjustments that we choose to make at this time, as well as some additional advice regarding how to navigate this time period effectively:

  • Jupiter in Aquarius is in a trine (120°) to the conjunction (0°) between the Sun and Mars in Libra. Jupiter is also in a sextile (60°) to the Moon.  Because Jupiter has just completed its annual retrograde phase (as of Sunday, October 17), that means that it is ready to actively support us in adapting to any changes, especially those that might result in increased independence, service to others, and/or becoming more aligned with our ethical principles.  If decisions need to be made, Jupiter will help us make them by providing us with the energy to achieve our goals and to overcome any obstacles.  We may also feel optimistic about the future and ready to initiate something new.
  • However, we do need to be careful about how we use our words during this time due to an opposition (180°) between Mercury and Chiron. If we don’t think through what we plan to write or speak before the message is delivered, we may end up feeling more vulnerable.  Misunderstandings are possible, most often due to taking things too personally.  Luckily, Mercury has ended its retrograde motion and is now moving direct again (as of Monday, October 18), so we should slowly see an improvement in our ability to express our thoughts clearly and to accurately perceive what others are saying to us.
  • Chiron is in a supportive trine (120°) with Venus, which will help us heal our relationships and support us in learning from each other.
  • Additionally, Saturn is in a trine (120°) to Mercury and a sextile (60°) to Chiron. This will help us think realistically, get organized, and tap into our past wisdom while making responsible, long-term plans for the future.  Although our conversations may be more serious and practical than usual, they have the potential to heal old wounds.

I do want to mention that many astrologers discussing this Full Moon are mentioning that the dwarf planet Eris is conjunct (0°) the Moon.  This means it’s also in opposition (180°) to the Sun/Mars and squaring (90°) Pluto.  Eris is named after the Greek goddess of strife and discord.  Having it involved in this cardinal t-square could cause us to be more impulsive than usual or act in a rebellious way.  However, the advice provided above still applies and will help us navigate this time period.  The good news is that Eris can add elements of self-reliance and strength, which are both helpful during times of change.  We just need to avoid the lower expression of Eris’s energy, which can include being resentful, bitter, or easily annoyed.

The Sun will move out of Libra and into Scorpio on Friday, October 22.  While transiting through Libra, the Sun simply wanted to keep the peace and to be fair and gracious.  Now that it’s in Scorpio, its goal is to unearth anything hidden in the darkness.  The goal is to bring it into the light (Sun) where it can be revealed and then healed (Scorpio).  During this time, we often aren’t satisfied with anything that is superficial.  Most of us will long for depth and intimacy in our relationships and in our emotional world.  Keywords right now would be intense, strong-willed, and passionate.  However, we do need to consciously choose to avoid Scorpio’s darker side, which can include behavior that is manipulative, jealous, or vindictive.

On Saturday, October 30, Mars will move out of Libra and join the Sun in Scorpio, where it will remain until mid-December.  Mars wasn’t comfortable in Libra, but it’s very happy in Scorpio.  Before the discovery of Pluto, Mars was the ruler of Scorpio.  Mars now feels it has free reign to move forward in a driven, single-minded, focused way to get what it wants.  It’s particularly interested in exploring deeper levels of our inner emotional worlds, and we will likely be more willing to unearth and face difficult topics.

Overall, this Aries Full Moon is going to be a very dynamic and energized time.  It will be important to make sure we aren’t overly stimulated and take action to vent some energy if we notice that we are becoming agitated, tense, or angry.  But any changes occurring now are meant to clear out old energy and bring in new energy that will lead to powerful opportunities to heal.  Admittedly, sometimes it hurts to rip the bandage off, and we should, therefore, be compassionate with ourselves and others through this process.  Although change can feel frightening, some of us may actually find that we have the courage we need to move forward and that we may do so with much less anxiety than we anticipated.  In fact, we may find that we are more than ready for this next chapter in our lives.
