To concentrate implies bringing all your energy to focus on a certain point; but thought wanders away... Whereas attention has no control, no concentration. It is complete attention, which means giving all your energy, the energy of the brain, your heart, everything, to attending.
People must work things out for themselves. It is no good saying, "I have found a house which suits me and therefore everybody must adopt the same kind of house."
Without total freedom, every perception, every objective regard, is twisted. It is only the man who is totally free that can look and understand immediately. Freedom implies really, doesn't it, the total emptying of the mind. To completely empty the whole content of the mind — that is real freedom.
Find out what it means to die - not physically, that's inevitable - but to die to everything that is known, to die to your family, to your attachments, to all the things that you have accumulated, the known, the known pleasures, the known fears. Die to that every minute and you will see what it means to die so that the mind is made fresh, young, and therefore innocent, so that there is incarnation not in a next life, but the next day.
It is utterly and irrevocably possible to empty all hurts and therefore to love, to have compassion. To have compassion means to have passion for all things, not just between two people, but for all human beings, for all things of the earth, the animals, the trees - everything the earth contains. When we have such compassion we will not despoil the earth as we are doing now and we will have no wars.
Understanding does not come through analysis;understanding comes only when the mind is very quite,unburdened,no longer seeking success and therefore being thwarted,afraid of faluire.
