Self-knowledge is not clarity or transparency or knowing how everything works, self-knowledge is a fiercely attentive form of humility and thankfulness, a sense of the privilege of a particular form of participation, coming to know the way we hold the conversation of life and perhaps, above all, the miracle that there is a particular something rather than an abstracted nothing and we are a very particular part of that particular something.

Knowledge of self ought to be the great project of our lives. Knowing ourselves we will know others. Only by knowing ourselves can we begin to undo the madness we unleash on the world in our wars, our destruction of the environment, our divisions, our desire to dominate others, the poverty we create and exploit. Only through self-knowledge can we reverse the damage we do with all the worldly knowledge we have, which has been only a higher ignorance.

Actually, an important part of self-knowledge is that it gives one a better realization of the inner strength that can be called upon, of which one may be quite unaware.

Knowing yourself is step one. Step two is acting on that knowledge.

Self-knowledge involves relationship. To know oneself is to study one self in action with another person. Relationship is a process of self evaluation and self revelation. Relationship is the mirror in which you discover yourself - to be is to be related.

Self-knowledge is the beginning of self-correction.

"Know your heart - whether it is good or evil, whether the source of your actions is pure or impure. Know what can be imputed to you and what belongs to your moral state, whether as something inherent in man's substance or as something derived (acquired or admitted).
Moral self-knowledge, which requires one to penetrate into the unfathomable depths and abyss of one's heart, is the beginning of all human wisdom. For wisdom consists in the harmony of the will of a being with his final end, and in the case of man this requires him first to remove the inner obstacle (an evil will actually present in him) and then to develop his inalienable and inherent disposition of a good will. "Only the descent into the hell of self-knowledge can pave the way to deification.

The first product of self-knowledge is humility,

To know oneself is the beginning of wisdom.

The transformation of the world is brought about by the transformation of oneself, because the self is the product and a part of the total process of human existence. To transform oneself, self-knowledge is essential; without knowing what you are, there is no basis for right thought, and without knowing yourself there cannot be transformation. One must know oneself as on is, not as on wishes to be, which is merely an ideal and there for fictitious, unreal; it is only that which is that can be transformed, not that which you wish to be. To know oneself as one is requires and extraordinary alertness of mind, because what is, is constantly undergoing transformation, change; and to follow it swiftly the mind must not be tethered to any particular dogma or belief, to any particular pattern of action. If you would follow anything, it is no good being tethered. To know yourself, there must be the awareness, the alertness of mind in which there is freedom from all beliefs, from all idealization, because beliefs and ideals only give you a color, perverting true perception. If you want to know what you are, you cannot imagine or have belief in something which you are not. If I am greedy, envious, violent, merely having an ideal of non-violence, of non-greed, is of little value. The understanding of what you are, whatever it be – ugly or beautiful, wicked or mischievous – the understanding of what you are, without distortion, is the beginning of virtue. Virtue is essential, for it gives freedom.

Knowing yourself is the beginning of all wisdom. — Aristotle

Self-knowledge is the beginning of wisdom, which is the ending of fear.

To know oneself is to study oneself in action with another person.

All knowledge leads to self-knowledge.
