Why do I want to remove emotion?
One point is that if I am caught up in emotion, I cannot see clearly or take wise decisions. If my mother is sick and dying, and I'm caught in emotion, full of my own sadness and grief, how can I think of how best to help her, how to lift her spirits and make her comfortable?
Can a person who is sad, anxious, or angry make a choice based on wisdom?
I see in myself that anytime there is an emotion arising from something I hear, touch, see, or feel, it means I have made a Self, an ego with something, it means I'm attached to something. Who gets angry? Who gets hurt? Why am I sad? Any emotion, particularly negative emotion, arising from a contact through one of the sense doors, means attachment to something, no? If I want to practice detachment, I should not accept the emotions born from it.
My understanding of equanimity is that it means that you are not a yoyo, getting delighted and excited with one word, depressed and unhappy with another. "You're beautiful" => happiness, "you're ugly" => insecurity/irritation. You don't depend on anything outside to bring you joy and happiness, you create it from inside when you meditate and depend on yourself.
I don't understand it to mean indifference, in the sense of not caring and therefore not wanting to help anyone who is suffering. It's selfishness that doesn't care about the suffering of others and doesn't want to help, while perfect equanimity is possible only for someone who is selfless. This equanimity can help to the maximum of his capacity, but doesn't get emotionally involved.
We have an image of a kind of psychopath that can murder someone without feeling a hint of guilt or emotion in relation to that, and so we're scared of turning into robots with no emotion, but the psychopath acts with indifference, not equanimity. He's selfish, so if he has something he wants removed from him, he'll get pissed off. The Buddha is the most compassionate and lovely person in the history of humanity, but you never hear of him getting emotional. If you're so full of compassion and generosity towards the whole world, if you're totally selfless, then you will be just content in yourself, you don't need some pleasant event from outside to bring you into pleasant emotion, and you don't fall into negative emotion with one word, look, or rainy day. This is the meaning of equanimity as I understand it.
One of my favourite teachings of the Buddha is when he tells "Even if someone is cutting you into pieces with a two-handled saw, if you have one thought of anger, you are not my student." He doesn't say that one should be aware of the anger, or that the anger is part of the human experience, he says that even in this most extreme situation, anger is not acceptable.
From my own experience, I can say that learning this practice of dropping the emotion in the present moment as I see it being born has helped me A LOT to be a better person. Let's say I have some problem that normally would cause me great anxiety and stress. Instead of carrying around anxiety, insecurity or stress all day long and constantly having to fight with it, I just drop it right away; then I'm light, and I can look at the problem and see if there is anything I can do about it - if not, I just continue and live with it; and if there is something I can do, I calculate what is the best solution, and do it.
I also never realised how much energy emotions demand; and when you are removing them, you have so much more energy. But as I said I'm far from being able to do it perfectly and all the time, this is the work of my life!

I thought that this was what meditation was for, actually; at least this was the meditation I learned. Do no others do this?
