There are three kinds of brains: One understands of itself, another can be taught to understand, and the third can neither understand to itself or be taught to understand.
You are this, which does not satisfy, so you want to be that. If there were an understanding of this, would that come into being? Because you do not understand this, you create that, hoping through that to understand or to escape from this.
Regarding this Dhamma, it is not something that we can simply talk about or take another's word for it. We need to develop meditation so that the understanding arises clearly within oneself. It is not the case that merely by listening to another's explanation our defilements will disappear. When we gain some understanding we need to chew on it again so that we see it for ourselves with certainty: paccattam.
There may be men who act without understanding why. I do not. To listen much, pick out the good and follow it; to see much and ponder it: this comes next to understanding.
When an individual passes from one period of life to another a time comes when he cannot go on in senseless activity and excitement as before, but has to understand that although he has out-grown what before used to direct him, this does not mean that he must live without any reasonable guidance, but rather that he must formulate for himself an understanding of life corresponding to his age, and having elucidated it must be guided by it. And in the same way a similar time must come in the growth and development of humanity.
Some men spend a lifetime in an attempt to comprehend the complexities of women. Others pre-occupy themselves with somewhat simpler tasks, such as understanding the theory of relativity!
Aloneness is obviously not isolation, and it is not uniqueness. To be unique is merely to be exceptional in some way, whereas to be completely alone demands extraordinary sensitivity, intelligence, understanding.
