Man's inability to understand and appreciate the thought and viewpoint of another man would be a stumbling block which no amount of mechanical ability could overcome.

MAN’S ONLY LIMITATION, within reason, LIES IN HIS DEVELOPMENT AND USE OF HIS IMAGINA­TION. He has not yet reached the apex of development in the use of his imaginative faculty. He has merely discovered that he has an imagination, and has commenced to use it in a very elementary way.

But the older he grew and the more intimately he came to know his brother, the oftener the thought occurred to him that the power of working for the general welfare – a power of which he felt himself entirely destitute – was not a virtue but rather a lack of something: not a lack of kindly honesty and noble desires and tastes, but a lack of the power of living, of what is called heart – the aspiration which makes a man choose one out of all the innumerable paths of life that present themselves, and desire that alone.

Because people who couldn’t imagine themselves capable of evil were at a major disadvantage in dealing with people who didn’t need to imagine, because they already were.

As vocabulary is reduced , so are the number of feelings you can express, the number of events you can describe, the number of the things you can identify! Not only understanding is limited, but also experience. Man grows by language. Whenever he limits language he retrogresses!

Difficulty shows what men are.

When men, engaged in unjustifiable pursuits, are aware that obstructions may come from a quarter which they cannot control, they will often be restrained by the bare apprehension of opposition, from doing what they would with eagerness rush into, if no such external impediments were to be feared.

Attachment to views is the greatest impediment to the spiritual path.

It is a mistake to suppose that the whole issue is how to free man. The issue is to improve the way in which he is controlled.

A general limitation of the human mind is its imperfect ability to reconstruct past states of knowledge, or beliefs that have changed. Once you adopt a new view of the world (or of any part of it), you immediately lose much of your ability to recall what you used to believe before your mind changed.

For men to plunge headlong into an undertaking of vast change, they must be intensely discontented yet not destitute, and they must have the feeling that by the possession of some potent doctrine, infallible leader or some new technique they have access to a source of irresistible power. They must also have an extravagant conception of the prospects and potentialities of the future. Finally, they must be wholly ignorant of the difficulties involved in their vast undertaking. Experience is a handicap. The men who started the French Revolution were wholly without political experience. The same is true of the Bolsheviks, Nazis and the revolutionaries in Asia. The experienced man of affairs is a latecomer.

The richness of the human experience would lose something of rewarding joy if there were no limitations to overcome.

There is a difficulty with only one person changing. People call that person a great saint or a great mystic or a great leader, and they say, 'Well, he's different from me - I could never do it.' What's wrong with most people is that they have this block - they feel they could never make a difference, and therefore, they never face the possibility, because it is too disturbing, too frightening.

Man’s imperfect, limited-capacity brain easily drifts into working with what’s easily available to it. And the brain can’t use what it can’t remember or when it’s blocked from recognizing because it’s heavily influenced by one or more psychological tendencies bearing strongly on it … the deep structure of the human mind requires that the way to full scope competency of virtually any kind is to learn it all to fluency — like it or not.
