The Ace of Swords is the Root of the Powers of Air and has affinity with the energy of Air. It represents inspiration, brilliant ideas and a new mental direction. Out of all the Aces, this one is the one that tends to come up the most in my readings.
It really underlines to me the importance of our thoughts - my own belief is that it is our thoughts that create our reality, and so the other suits naturally follow from this one; the Cups tells us that out of our thoughts about how loveable we are, we create the experience of love in our lives; out of our thoughts about what is possible for us, we create opportunities, adventures and experiences and so we have the Wands to inspire us; out of our thoughts about how valuable we are, we create value for ourselves and the Pentacles will count this out for us.
The Swords Suit brings in the element of Air and the mental realm. The Ace is the powerful upsurge of ideas, thoughts and decisions that guide our direction. With the Ace we have the most potency and potential, so this is the stage where you need to set and guide your thoughts to create in your life everything that you want to experience - it is the Seed that will be fulfilled by the energy that you pour into it.
The Sword is a tool and it is also  a weapon. Talk about duality, and balancing on the edge of a knife! Know that your primary focus is what determines the good or ill that comes to you eventually. Since the Sword is a tool or a weapon, it does not have a mind of its own, it must be directed. Do you have the courage to decide your own future? Or are you at the mercy of the thoughts, beliefs and machinations of others?
It is time to awaken to the power of your own mind and decide what you will do with this power.
