Detachment
It is a concept that really bothered me. I understood the cruelty of detachment when I saw the last Star Wars movie. When Yoda told Anakin that he had to be detached from what he loved, I really wanted to punch him on the face. Such lack of understanding and compassion was absolutely deplorable for me. And this is what bothers me with Buddhism as well.
And now, those last days, I feel myself increasingly detached from many things. Am I being cruel to myself? This is a possibility. In any case, if I feel detached, it is my own need, and nobody's claim that I HAVE to be detached. Then, if I consider detachment only as a satisfaction of a need and not a necessity, it is just a psychological state and not a philosophical one. It can easily turn to abandon and depression. And in any case, I don't want detachment to be only an expression of cowardice and lack of energy.
When I think of detachment now, I think of Sasuke: it permits him to say what he really thinks, without caring if he is going to be misunderstood. It also permits him to be concentrated on his goal and analyse things from a distance. He can remain calm in most situations. Yet, he is not detached from his goal, he remains combative and energetic. And still, he cares. He will show interest when there is a purpose.
