These are overall Transit energies that must absolutely be nuanced according to your own birth chart, see the article on Neptune in transit; for interpretation of your natal Neptune, see Neptune in birth chart.
This is a transit with a certain depth and slowness, since it spends approximately 14 years per sign, and can initiate profound, foundational transformations of the personality.
Neptunian energies strongly represent forces of transpersonal emotional openness, of heightened receptivity.
They can rhythmically activate important spiritual qualities, notably, significant forces of “dissolution”, mysticism, and universality.
Spiritual and Universal Opening
This is an angular transit that clearly carries major evolutionary weight over the course of a lifetime !
The passage of Neptune over the Ascendant definitely warrants closer attention, as it’s as though the planet here “emerges into consciousness”, and from that point forward, its energies feel a much stronger need for expression through the personality.
For instance, there may be the emergence of a new spirituality, or at the very least, a need to more fully claim it, to exteriorize it, to draw closer to it.
This can manifest, notably, in a need to align more closely with “a vocation”, with artistic (imaginative) or devotional facets, or in gaining perspective in relation to that which is greater than oneself.
It can render one generally more “receptive” and emotionally sensitive (a bit of a “sponge” quality), bringing with it, then, the need to put these forces into action in daily life, in one’s drive for self-realization, in personal projects.
It can also make one more “cyclothymic”, with greater difficulty anchoring these feelings, and moods that fluctuate more readily.
It remains important to channel emotional forces as effectively as possible, for example, through techniques such as meditation, breathwork, prayer, or various practices aimed at “inner calming”.
Also take care: the forces of dissolution are maximized on the personality, and this can prove quite antagonistic to the very nature of the Martian Fire of this sector (this is a transit that renders one less self-centered, more altruistic, etc, so personal assertion becomes, in a sense, more diluted), almost as though it brings present-day self-realization closer to a Pisces archetype.
It can also make one more readily idealistic or dreamy, while increasing a certain passivity or confusion around the personal goals being pursued.
It remains essential to skillfully articulate this transit with the various natal Earth forces, but also, notably, with the forces of the current Saturn transit, which can help ground these abstract energies in tangible reality.
A transit of retrograde Neptune in the 1st House or in Aries can render one more introspective and receptive during this retrograde period.
It’s important to contextualize this Neptunian transit within the full arc of its retrograde phases and its returns to direct motion, which can, of course, place greater emphasis on specific points in our birth chart, particularly during the stationary phases that last several weeks…
