A complex chart such as this is bound to create variable difficulties in the life, especially since it involves a grand cross in the fixed signs. This intense configuration involves security, resources and self-worth. A Grand Fixed Cross deals with security, resources and self-worth.
The energies work at cross purposes, which makes for a lot of confusion and instability, especially in the younger years. The purpose here is that you have a lot of 'inner work' to undertake in order to gain a greater sense of control and power in the life. You have a lot of karmic energies at work here, which basically means that the psyche has a lot of carry over baggage from your genetic and childhood influences.
You are prone to being emotionally repressed [Saturn/Moon, with Capricorn ruling the 4th]; this stems from your early conditioning and imprinting from the family and relatives. The Moon represents the Mother, and her influence may be at the heart of your inner sense of repression and uncertainty. You are being called to address your emotions more directly and gain an understanding of their purpose in our lives.
'Emotions are the river upon which our memories from the past are carried forward into the future we are creating.' They represent the foundations of our actions, and reactions, in the outer world which are at the seat of our external experiences [the law of cause and effect]. Our challenge in life is to learn to be aware of our emotions and learn to control them, rather than having them control us.
More often than not, people believe that we control our world through the mind, while in truth we often allow the emotions to control us through our perceptions and subsequent actions. This represents the differentiation between our conscious workings and our subconscious. The Moon in Scorpio is emotionally intense and seductive, making one sensitive and possessive, especially when feeling out of control. This Moon often creates an air of mystery which can be interpreted as suspicion by many.
Intersecting this polarity is another opposition between Mercury and Neptune which causes it's own share of confusion, indecision, deception or disillusionment.
Your Sun is also afflicted by Uranus which can easily cause a distortion of your sense of personal Identity. Uranus is a disruptive energy; you can vacillate between being a rebel or a revolutionary; it demands independence but also induces sudden changes that can cause destabilization. This represents your 'hit to the ego' from the past, which may be associated with the father's influence or other male influences.
Saturn in the 8th H can definitely relate to sexual repression, and since Mars in Cancer is in detriment, this too can hold you back from expressing your sexuality in healthy ways, especially in view of your Mothers inhibiting influence and perhaps due to family values, beliefs and taboos.
Still you do have an out-of-sign grand trine, which may ultimately help to offset the challenges in your life, especially in later life, if you attend to gaining greater self-awareness and work on the inner complexes that hold you back.
