…Neptune in Aries We will feel more with Neptune in Aries especially when he enters Aries, when he exits it and goes back to Pisces, and then goes again into Aries. We will feel it more when he will make strong aspects with mars and with planets in cardinal signs. Now when he enters Aries and goes back to Pisces and then goes back to Aries this happens on the world axis (29° of mutable signs to 2-3° of cardinal signs) meaning that thing will happen the world stage, visible from everyone, they are brought OUT visibly.
Interestingly when Neptune enter Aries in a definitive way, on the 20th of February 2026 he’ll be conjunct Saturn at 0° of Aries, so we have also to take in account how this plays out because it’s not possible to separate the two events. The two have a synodic cycle that is about 36 years, but the chances that the conjunction happens at 0 degrees of Aries is minimal; and as I say this I have chills. 0° of Aries, it’s the start of a new age, a new time, a new epoch, not saying good or bad, but it’s for sure a NEW BIG CHAPTER STARTING. Aries is the first sign of the zodiac wheel, and the soul (Neptune) and the boundaries (Saturn) of mind, spirit and body, enter together into this sign. I almost cry as I say/write it.
First they test the waters each by their own, in 2025, and then together they move into Aries, in a way that will be seeable and palpable by the whole world. This can play out in a number of ways of course but just know that on the 20th of Feb, when they enter in Aries, the Mooooon I mean.. the Mooon (the people feeling this individually and collectively, when the Moon is involved in a big event it means that the people are involved in it as well) will also be in Aries AND Mars will be in Pisces!! Therefore in mutual reception with Neptune! We aim for higher goals, higher purpose, the strength of Mars is directed to the celestial, and the celestial inspires Mars.
And that day Jupiter in Cancer will be trining with a 3-5 orb degree both Venus and Mercury

But let’s now just imagine Neptune, a watery, deep, powerful god entering the land of Aries, the domain of Mars, what does it all mean? Neptune rules many things: first of all it represents the Chalice of the Soul, endless and boundless love, perception, sensation and it also rules art, film industry, creativity, deception, illusions, poisoning, virus, maladies, malaise, epidemics, but also deep healing, high ideals, vision, mysticism, spirituality, libraries, prisons, hospitals, cinemas, escapism, drugs, addictions, alcohol, mental health, esoteric experiences, the water, the seas, blood, immune system, lymphatic system, fusion with the other, self-soothing and ultimately I’d say the Valley of the Soul-Making, to quote John Keats. And in this case, with Saturn together entering Aries with Neptune this quote takes even a more specific meaning:
The Valley of the Soul (Neptune) - Making (Saturn).
Again a reference of the two co-operating and starting a new big chapter together.

Aries is the first assertive power of the incarnated existence, without yet knowing the borders and limits of the body, without knowing containment. Neptune also dissolves the boundaries and knows no limits. So this boundlessness is what the two (Neptune and Aries) have in common, no limits and no containment. It could very well be that this entrance of Neptune in Aries supports the assertion and manifestation of the Soul and its deepest desires in a fierce and strong way, but it could also mean that the domain of Aries meaning wars, attacks, battles, and fights are acted through the means of Neptune: viruses, distorted-spirituality, invisible poisons and such.

Neptune rules the blood and the lymphatic system, while Neptune is in Aries it suggests and encourages us to strengthen and power up our immune system through many ways and amongst the different you can think of and I see this process happening through our individuation, and the birth of the individual Self, with/through our sense of adventure, sense of freedom, creativity and DISCOVERY of the Self in new ways.
In this way that we strengthen and fortify our Immune System. The Burning Soul, blazing through the Body, energising it, and making it ALIVE. 
Now, since Neptune is the Soul and is linked to blood and Aries is also connected somehow to blood and fire and assertiveness, this tells me that The Soul needs to enter the blood and be manifested through our action, through our presence, through our healthy sacred holy individuation and identity and in this way we will also be able to find the soul principle in our primal needs met, it’s like an infusion of Soul in every action.
At the beginning there can be some confusion (Neptune in Aries is similar to Mars in the 12th House) but Saturn entering together in Aries with Neptune gives structure and determination where Neptune alone could be too idealistic, dispersive, and fantasising or sublimating and transcending primal important movement of our individuality.

But we also can take in account that this duo-entrance in Aries can also mean that wars, (Aries, Mars domain + Saturn in Aries militarisation) can be undertaken for spiritual ideals, so Neptune in Aries could also manifest itself in wars triggered by religions and “spiritual views”. But it can also mean that if everyone gets in touch with their own own real, personal, holy, sacred spirituality, this will help FORGE a new path ahead and a new world. Saturn is responsibility and together Neptune in Aries they say, “forge don’t follow”. Our personal self actualisation and spiritual discovery during our life is the real and only battle we can do to manifest (Neptune) a different world and structures (Saturn), and oftentimes this happen without even us wanting it so consciously (Neptune rules the unconscious and Soul realm). Meaning that when we follow our spring, our inner voice, our inner intuition, our inner flame (Aries) we manifest our visions (Neptune), and with Saturn we can be really dedicated and responsible in doing this and we get to be each the leader of ourselves. In shining and giving ourselves to the world we actually inspire others to do the same, in their own way and hence a new world can and will take shape. 

Aries in the primal intuitive function, Aries does not think , Aries has inner hunches that prompt them to the action. Aries is action oriented. Neptune is psychism, so intuitive action + psychism and collective unconscious is likely to result and manifest in telepathy also and heightened psychic faculties of many kinds.

On another note Neptune in Aries could also be that many rebellions will happen in those environments like prisons, hospitals, mental houses, and such and/or for reasons connected to the themes related these environments (freedom, justice, health, churches also and charitable related entities, think about UN (United Nations) for example and the corruption that lurks in there as well.

I also sense that many souls around the world will start to stand up for themselves and assert themselves finding their own way to manifest their being, because remember that Neptune dissolves what it touches but also it gives it vision, faith, and a sense of expansion of the Soul; In the Long Run I can imagine Neptune, together with Saturn dissolving Aries most egotistic-drive principle allowing the individual to be the sovereign of their essence in a creative way, empowering way for the individual and for the collective. 

Saturn in Aries also tells me of militarisation, or being the chief of your own flame. It depends how to handle that, and what aspects of course it makes in your natal chart.

Marine wars, this also could be a possibility linked with Neptune in Aries and Saturn in Aries.

Other things that came to mind in the regard of this event and process.

“Waves of heat coming, not knowing where they’re coming from.”The forming Principle of the Soul. (In the beginning Rudolph Steiner said that souls were ethereal and undefined “balls of fire”)
Fevers, purification of the blood through heat and fire.
Waves of heat and feelings pushing up, piercing through the veils of uncertainty into expansion, creative revelation of the inner flame that dwells in each of us.
Underwater volcanoes 

New life that emerges from underwater (and with Sedna soon (2026) Conjunct Uranus in Gemini this is wohooo and might be linked also to … E.T. contacts coming from both the Space AND from Underwater, it’s well known amongst e.t. researchers that there are many hidden e.t. bases within the earth but also in the deep deep ocean!!) Neptune at 0 of Aries will be in a sextile (!!) with Uranus and Sedna in Gemini in 2026
Hope and wish these consideration give you some insights or interesting pondering / reflections.
