Pluto will enter into your 12th house Pisces. This is an area of life related to isolation, renunciation, spirituality removed from religion, hidden enemies, sorrows and losses. Coming to terms with how you connect to spirit, the primordial essence of existence might develop over the decades.
This could unlock certain sensitivities such as psychic phenomena, any manner of unusual non-physical experiences. If you do have these it is a good idea to seek support, a professional who can guide you through it.
There might be events or a general process of coming to surrender your sense of control and accept the greater forces and circumstances that direct you. It is a time where going deep into the subconscious can be of great benefit, through therapy or other healing modalities.
Alternatively, Pluto could be asking that you come to find peace with yourself by learning how to be alone without being lonely, so developing a meditation practice or anything that helps you to manifest this consciously will be of great benefit.
You may have some issues arising during this time with people working against you or your aims – this might not be intentional, just recognising that sometimes two people are at cross-purposes. If Pluto touches sensitive natal placements you might experience loss.
Pluto might affect your 6th house if you have important placements in Leo. It is good to take care of your health, do your routine check ups, follow medical advice. If Pluto triggers that house for you it is to point you in the direction of better routines.
Generally it could just mean significant changes in your routine, to give you more alone time or to accommodate situations out of your control. You may want to be of service to others but be careful to balance this with sufficient self-care. Taking good care of yourself will enable you to be helpful – as in the airplane – put your oxigene mask first.
Pluto also squares your 9th (Scorpio) and 3rd (Taurus) WS houses. This will be much more noticeable if you have planets there. Pluto aspecting the 9th asks us to reassess the meaning of life, our purpose and the social and religious structures that support this. Processes of fighting your inner demons, coming to terms with loss or even health issues might push you towards a new form of religion/spirituality or extensive travel. For some of you it might bring you to decide to study a completely new subject.
Finally, aspecting the 3rd suggests your local environment and neighbourhood might go through significant changes. This could also impact siblings and extended family in some way or just your relationships to them. It also deals with writing, learning and communication so you could see this being emphasised when Pluto aspects a planet here. Alternatively earth-based spirituality and rituals could become prominent.
