Eclipses: Pisces and Virgo Set the Pace

Full Moon + Lunar Eclipse in Pisces (September 7)

This lunar eclipse emphasizes emotional closures, the release of old patterns, and heightened sensitivity. Pisces opens the door to compassion, faith, and forgiveness, inviting you to let go of idealizations and reclaim creative energy. It is a culmination point for processes that began with the New Moon in Pisces months ago.

Practically speaking, this is an excellent time for closing rituals, conscious rest, and using artistic expression as a bridge to healing. Avoid reactive decisions; perception is amplified, but so are projections. Pay attention to your energetic boundaries and prioritize restorative sleep.

Tips: Stay hydrated, reduce digital stimulation, write down what you need to release, and make space for contemplation. If you are in therapy, honor your insights without judgment.

Solar Eclipse + New Moon in Virgo (September 21)

Virgo inaugurates a cycle of improvements, habits, and order. This solar eclipse signals a reset in health, daily work, systems, service, and efficiency. It’s time to edit processes, simplify workflows, and create sustainable routines that support your goals.

The energy favors personal audits: diet, rest, budget, task organization, tools, and metrics. It also boosts a drive for continuous improvement and quality in what you deliver.

Tips: Define three measurable habits for the next 30 days, clean your workspace, automate repetitive tasks, and create checklists to save mental energy.

Personal Planets: Adjustments in Mind, Bonds, and Action

Mercury in Virgo (Sep 2) → Mercury in Libra (Sep 18)

The first half of the month prioritizes precision: analysis, data collection, editing, and a focus on what is useful. It is ideal for closing pending tasks, documenting processes, and correcting errors. Avoid paralysis by perfectionism: “good enough” is what moves projects forward.

With Mercury’s entry into Libra, communication gains diplomacy, negotiation, and an aesthetic sense. It’s perfect for agreements, presentations, branding, and difficult conversations with a win-win approach.

Practices: Draft SOPs (Standard Operating Procedures), schedule key meetings after the 18th, prepare arguments with data, and use active listening to resolve points of friction.

Venus in Virgo (Sep 19)

Love is expressed through details and acts of service. In finances, this transit calls for order, small optimizations, and intelligent purchases. In aesthetics, it favors minimalism and functionality. Beware of excessive criticism; it’s better to turn it into constructive feedback.

Relationships benefit from shared wellness routines (eating better, working out, organizing). Practical self-care is highlighted: medical check-ups, an updated schedule, and adequate rest.

Practices: Create a weekly budget, review subscriptions, declutter your closet, and practice micro-rituals of presence with your partner or team.

Mars in Scorpio (Sep 22)

Action becomes deep, strategic, and intense. This is excellent for research, complex negotiations, transforming habits, and emotional purification. It requires honesty and prudence: well-channeled passion yields results; resentment leads to stagnation.

Avoid unnecessary power struggles and the urge to over-control. Use Scorpio’s strength to get to the root of the problem, not just to win for the sake of winning.

Practices: A digital and physical detox, somatic work, milestone-based planning, and setting clear boundaries on your time and energy.

The Sun in Libra: Balance and the Autumn Equinox (Sep 22)

The equinox marks a point of balance between light and shadow. Libra highlights agreements, justice, aesthetics, and intelligent collaboration. It’s a season to review the balance between giving and receiving, between beauty and functionality, and between personal desire and the common good.

In business, co-creation and experience design will thrive. Personally, focus on nurturing your relationships and shared spaces.

Practices: Renegotiate expectations, beautify your daily environment, and define clear rules for cohabitation or projects.

Slow-Moving & Retrograde Planets: Foundation, Structure, and Purpose

Saturn Retrograde in Pisces (from Sep 1)

This is a time for reviewing healthy boundaries, spiritual commitment, and compassion with structure. Saturn demands responsibility for your sensitivity: sustainable rituals, gentle discipline, and clarity in the intangible.

In creative or service-oriented projects, establish clear containers and timelines. Less vague sacrifice, more service with defined edges.

Practices: Keep a spiritual schedule (meditation, journaling), set agreements on your availability, and use small metrics for well-being.

Uranus Retrograde in Gemini (from Sep 6)

It’s time to adjust recent changes in communication, learning, technology, and networks. Review your information systems, data security, and content consumption. The mind calls for innovation with cognitive ergonomics.

Avoid noise and experiment in a sandbox environment before scaling up. Pay attention to your body: breath and sleep regulate the mind.

Practices: Digital cleanup and backups, limit notifications, and engage in learning sprints with clear objectives.

Neptune and Pluto Retrograde (all month)

Neptune retrograde sharpens spiritual discernment: less escapism, more presence. Pluto retrograde purifies power, purpose, and belonging: where do you need to transform obsolete structures?

Both invite you to clarify your motivations, release fantasies, and sustain deep processes without rushing. Regeneration requires patience.

Practices: Therapy, shadow work, setting boundaries with idealization, and creating space for conscious silence.

Practical Checklist for September 2025

• Define three measurable Virgo-style habits (health, order, finances) for 30 days.
