Success depends on faith and good deeds... not upon the knowledge of the proofs which lead to them.

Illusion and self-deception stand in the way of an honest, penetrating and fearless self-appraisal. Though it would appear that we have access to the innermost core of our individual being, and that there is nothing in the world with which we are on more intimate terms than our own self, the self remains an elusive object of knowledge and understanding.

Desire for knowledge is the path of honor: desire for wealth is the path of dishonor. Wealth is the chain that slaves wear; knowledge the kingly crown.

Good is the cause of love, as being its object. But good is not the object of the appetite, except as apprehended. And therefore love demands some apprehension of the good that is loved... Accordingly knowledge is the cause of love for the same reason as good is, which can be loved only if known.

Knowledge is in inverse ratio to materiality... Moreover, among the senses, sight has the most perfect knowledge because it is the least material... while among intellects the more perfect is the more immaterial.

The intellectual soul, because it can comprehend universals, has a power extending to the infinite; therefore it cannot be limited by nature either to certain fixed natural judgments, or to certain fixed means whether of defense or of clothing, as is the case with other animals, the souls of which have knowledge and power in regard to fixed particular things. Instead of all these, man has by nature his reason and his hands, which are the organs of organs, since by their means man can make for himself instruments of an infinite variety, and for any number of purposes.

When... the thing in which there is good is nobler than the soul itself, in which is the idea understood, by comparison with such a thing the will is higher than the intellect. But when the thing which is good is less noble than the soul, then even in comparison with the thing the intellect is higher than the will. Therefore the love of God is better than the knowledge of God; but, on the contrary, the knowledge of corporeal things is better than the love of them. Absolutely, however, the intellect is nobler than the will.

Spiritual knowledge cannot be communicated from one intellect to another, but must be sought for in the spirit of God.

Willingness to be taught what we do not know, is the sure pledge of growth both in knowledge and wisdom.

There is no knowledge for which so great a price is paid as a knowledge of the world; and no one ever became an adept in it except at the expense of a hardened or a wounded heart.

It is our duty to give meaning to the life of future generations by sharing our knowledge and experience; by teaching an appreciation of work well done and a respect for nature, the source of all life; by encouraging the young to venture off the beaten path and avoid complacency by challenging their emotions.

Whatever study tends neither directly nor indirectly to make us better men and citizens is at best a specious an ingenious sort of idleness; and the knowledge we acquire by it only a credible kind of ignorance, nothing more.

The knowledge beyond all other knowledge is the knowledge how to excuse.

Piety and selfless deeds elevate the inhabitants of this earth to exalted spiritual estates... self-serving acts reduce them to the realms beneath, of sorrow and pain, rebirths among birds and vermin, or out of the wombs of pigs and beasts of the wild, or among trees. Action is a function of character, which in turn is controlled by custom. This is the whole substance of the secret. This knowledge is the ferry across the ocean of hell to beatitude. For all the animate and inanimate objects in this world... are transitory, like dream. The gods on high, the mute trees and stones, are but apparitions in the fantasy. Good and evil attaching to a person are perishable as bubbles. In the cycles of time they alternate. The wise are attached to neither.

Real knowledge never promoted either turbulence or unbelief; but its progress is the forerunner of liberality and enlightened toleration.

Every branch of knowledge which a good man possesses, he may apply to some good purpose.

I am not collecting my knowledge from letters and books, but I have it within my own Self; because heaven and earth with all their inhabitants, and moreover God himself, is in man.

Through zeal knowledge is gotten, through lack of zeal knowledge is lost; let a man who knows this double path of gain and loss thus place himself that knowledge may grow.

Without knowledge there is no meditation, without meditation there is no knowledge: he who has knowledge and meditation is near unto Nirvana.

Not in the knowledge of things without, but in the perfection of the soul within, lies the empire of man aspiring to be more than man.
