Knowing is not entirely the wisdom of the universe, but more our own understanding and judgment. "Knowing and seeing" is a mixed word of knowing and seeing, that is, the knowledge and understanding of all laws, which refers to the individual judgment and choice of the self. To establish knowledge is to define it as a fixed knowledge, that is, various restrictions and definitions made by ourselves. It is precisely because of this limitation of self and this continuous separation of mind and mind that mistakes will be made. Ignorance is irrationality and wisdom. This book does not have to be understood as "the origin of ignorance" or "the root of ignorance", but as the essence and expression of ignorance. All kinds of thinking judgments and persistent choices about the outside world are the consequences of ignorance. The so-called: the mind gives birth to all laws, and the mind destroys all laws. Ignorance is actually a delusion in the heart, and various realms are born.

Therefore, all scientific, philosophical and other ideological understandings need to change and develop with the development of the times and the changes of vision and mind. There can't be eternal things in the world, everything is in impermanence. The law is always comfortable, but the angle and method of interpretation are different because of time and human feelings. All our cognitive behaviors are actually reflections of self-cognition, and there is no distinction between true and false. All opinions are not true reflections of the outside world, but only our own understanding of the outside world, so we say that idealism is illusory. Our "understanding" of all things and phenomena in the world is only based on what our own eyes, ears and even six heads can understand and accept. Many parts of Buddhism that we can't accept and can't accept can't appear in our consciousness. This is the limitation of "cognition".

Conscious thinking is limited, because it is the embodiment of our inner ability to accept, understand and judge. How much we know about the outside world is not obtained by the existence and changes of the outside world, but by how far we can go. As a wise man, we need to be cautious about thinking, the function of the language used to express thinking and the content of expression.

Therefore, Buddhism has always stressed the need to overcome all kinds of "self" persistence. In Buddhism, abstinence refers to five connotations of impermanence and four concepts of constancy. Therefore, taking falsehood as the truth, taking falsehood as the truth, and constantly thinking about it have all kinds of fantasies and concerns, so it is called "false persistence" and wrong persistence. Stubbornness, prejudice, one-sidedness, etc. Are arbitrary. In addition, diligence should still be needed. For example, we need to be diligent, earnest, confident and persistent in the progress of thought, the practice of Buddhism and the improvement of morality.

In fact, the ultimate truth will always exist by itself and will not really change because of our interpretation and the deviation of our perspective. When a Bodhisattva practitioner realizes that there is no gain, he realizes that all dharma circles are pure nirvana.
