"Pursue not the outer entanglements;
Dwell not in the inner void;
Be serene in the oneness of things;
And dualism vanishes by itself." (Jianzhi Sengcan, "Xinxin Ming", cca. 600)
"Since in reality all is void, Whereon can the dust fall?" (Dajian Huineng, cca 7th century)
"There is no Bodhi tree,
Nor stand of a mirror bright.
Since all is void,
Where can the dust alight" (Dajian Huineng, cca 7th century)
"Our original nature is [...] void, omnipresent, silent, pure; it is glorious and mysterious peaceful joy - and that is all. Enter deeply into it by awakening yourself." (Huangbo Xiyun) (Huangbo Xiyun, "Chuanxin fayao" ["Essentials of the Transmission of Mind"], 857)
"People are scared to empty their minds
fearing that they will be engulfed by the void.
What they don't realize is that
their own mind is the void." (Huangbo Xiyun, "Chuanxin Fayao" ["Essentials of Mind Transmission"], 9th century)
"The Great Void cannot but consist of ch’i; this ch’i cannot but condense to form all things; and these things cannot but become dispersed so as to form (once more) the Great Void." (Chang Tsai, "Zhengmeng" ["Correcting Ignorance or Rectifying Youthful Folly"], 1076)
"When one knows that the Great Void is full of ch’i, one realizes that there is no such thing as nothingness."(Chang Tsai, "Zhengmeng" ["Correcting Youthful Ignorance"], 1076)
"When it is understood that the Vacuity, the Void, is nothing but material force, then existence and nonexistence, the hidden and the manifested, spirit and eternal transformation, and human nature and destiny are all one and not a duality. He who apprehends integration and disintegration, appearance and disappearance, form and absence of form, and trace them to their source, penetrates the secret of Change." (Chang Tsai, "Zhengmeng" ["Correcting Youthful Ignorance"], 1076)
"To attain the Way of strategy as a warrior you must study fully other martial arts and not deviate even a little from the Way of the warrior. With your spirit settled, accumulate practice day by day, and hour by hour. Polish the twofold spirit heart and mind, and sharpen the twofold gaze perception and sight. When your spirit is not in the least clouded, when the clouds of bewilderment clear away, there is the true void." (Miyamoto Musashi, "Go Rin No Sho" ["The Book of Five Rings"], 1645)
"In grasping that one remark, Pang was able to complete his enlightenment. He saw that Uncritical Mind was not enough. His mind had to become as immense as Buddha Mind; it had to encompass all Samsara and Nirvana, to expand to Infinity’s Void. Such a mind could swallow the Pacific." (Xu Yun, "Empty Cloud", 1952)
"One man watches a river flow by. If he does not wish it to flow, to change ceaselessly in accord with its nature, he will suffer great pain. Another man understands that nature of the river is to change constantly, regardless of his likes and dislikes, and therefore he does not suffer. To know existence as this flow, empty of lasting pleasure, void of self, is to find that which is stable and free of suffering, to find true peace in the world." (Ajahn Chah, "A Still Forest Pool", 1985)
"Change is the end result of all true learning. Change involves three things: First, a dissatisfaction with self - a felt void or need; second, a decision to change to fill the void or need; and third, a conscious dedication to the process of growth and change - the willful act of making the change, doing something." (Leo Buscaglia, "Love", 1972)
"Fundamentally, our four elements are void and the five aggregates (skandhas) are non-existent. It is only because of (our) wrong thoughts which grasp (everything) that we like the illusion of the (impermanent) world and are thereby held in bondage. Consequently, we are unable to (perceive) the voidness of the four elements and (to realize) the non-existence of birth and death. However, if in a single thought, we can have an experience of that which is not born, there will be no need for those Dharma doors expounded by Shakyamuni Buddha." (Xu Yun, "Discourses and Dharma Words", 1996)
"Zen Buddhism emphasizes the concept of Mu, which symbolizes enlightenment. Mu is absolute nothingness that transcends the conflict between existence and non-existence. This notion defies comparisons with other concepts. Mu is existence itself. In Zen Buddhism, becoming mu means to grasp the ultimate nature of reality, which allows you to achieve enlightenment. Mu does not signify a blank state of mind; rather, mu represents detachment from the five organs of the body after understanding their functions. The concept of ku, on the other hand, may evoke the image of a void." (Kazumi Tabata, "Mind Power: Secret Strategies for the Martial Arts", 2010)
