In this card we see an armoured knight with his sword raised and a shield with a Lion on it. He stands above a purple beast who faces him. In front of the beast are human bones.
If you see the knights as being represented by air then this card is double air - so lots of mental energy. In the book place talks about the card representing decisiveness, positive-thinking and bravery. It also warns of being too impetuous and rushing into things with extreme force.
I think we see here a person who is prepared to fight for what they deem important. Willing to stand up for their beliefs (fight for their ideas and ideals, represented by the air of swords, and perhaps the air of Knights too). The lion on the shield seem an obvious representation for bravery.
I wonder what the significance of the colouring of the beast is? I think of this colour, violet, as being linked to the 7th Chakra and perhaps spiritual energy. I wonder how that fits in with this cards meaning? The beast seems to surround the knight but he seems undisturbed. He seems confident and preapred to stand up for his beliefs. Maybe the human bones are a warning of what is at stake if you give up your ideals!
