The Star is the Greatest Love there is. But it's often misunderstood. As Thirteen wrote - it's not a selfish kind of love. It is absolute, constant, healing and very beautiful.
One of my favourite books is called, simply, Arcanum 17. It was written by a great lover of tarot, the poet André Breton. It is entirely about love. It starts with the love he found with the woman who was to become his wife - and the love of his life - after his former wife had left him, taking their son away, and leaving him very raw. But it goes beyond that. Breton speaks of The Star card as the power of regeneration through love, and particularly, through a feminine kind of love. He writes that women are the salvation of the earth. He was writing this in the middle of the Second World War - a war started and largely fought by men - while his beloved France was occupied by the Nazis. Because he was a communist, he had to leave France, and found refuge in Canada with his new love - that's where he wrote Arcanum 17. And so finally, for him, the Star is the Love that Redeems the earth - what humans do to each other. The Tower in his life - his wife leaving him, the war, the occupation of France - these were all healed and redeemed by the power of the Love found in the Star card, which starts with a human, erotic love - and widens to encompass the whole of humanity and nature.
I've not yet read a better description/meditation of The Star card, and in particular, its capacity to heal and regenerate through love.
