"[...] so external sensation is the image of this perception of the soul, which is in its essence truer and is a contemplation of forms alone without being affected. From these forms, from which the soul alone receives its lordship over the living being, come reasonings, and opinions and noetic acts; and this is precisely where ‘we’ are." (Plotinus, "Enneads", cca. 270 AD)
"Zazen is seated meditation-the opposite of contemplation-the emptying of the mind of all thoughts in order simply to be. In the midst of all evil, not a thought is aroused in the mind-this is called za. Seeing into one's Self-nature, not being moved at all-this is called Zen." (Dajian Huineng, cca 7th century)
"If you would be free of greed, first you have to leave egotism behind. The best mental exercise for relinquishing egotism is contemplating impermanence." (Dogen Zenji, cca. 13th century)
"You must contemplate the Way of the warrior's skill so you will be able to beat a man in combat by the use of your eye. With diligent training, you will be able to beat ten men in combat by using your spirit." (Miyamoto Musashi, "Go Rin No Sho", 1645)
"As we contemplate the edifice of the universe, in its vastest extension, in its minutest divisibility, we cannot resist the notion that an idea underlies the whole, according to which God and Nature creatively interact forever and ever. Intuition, contemplation, reflection give us an approach to these mysteries, We are emboldened to venture upon ideas; in a more modest mood we fashion concepts that might bear some analogy to those primal beginnings." (Johann Wolfgang von Goethe, "Doubts and Resignation", 1820)
"It is not enough to contemplate ourselves objectively; we must also treat ourselves objectively." (Ernst, Baron von Feuchtersleben, "The Dietetics of the Soul; Or, True Mental Discipline", 1838)
"Religion and science are the two conjugated faces of phases of one and the same act of complete knowledge - the only one which can embrace the past and future of evolution so as to contemplate, measure and fulfill them." (Pierre T de Chardin, "The Phenomenon of Man", 1955)
"One method for calming the mind is to contemplate the transient nature of our thoughts. When you are aware that your thoughts arise and perish of their own accord, there will be no need to be ruled or conditioned by them. Your mind will settle into observing them with detached awareness and your emotions will become even. If you can do this, you will soon be able to pacify your mind." (Sheng Yen, "The Method of No-Method: The Chan Practice of Silent Illumination", 2008)
"The unknown, our own true nature, has the capacity to wake itself up when you start to fall in love with letting go of all the mental structures you hold onto. Contemplate this: there is no such thing as a true belief." (Steven Gray [Adyashanti], "Emptiness Dancing" , 2004)
"A rock pile ceases to be a rock pile the moment a single man contemplates it, bearing within him the image of a cathedral." (Antoine de Saint-Exupéry)
"Contemplation is to knowledge, what digestion is to food the way to get life out of it." (Tryon Edwards)
"Further, this power which conceives these ideas does at times gain from sense forms mental, imaginative, and innate in (instinctive to) itself; and in such a case it does this in that it lays before itself the forms that are in the conceiving power and in the remembering (preserving) power, by employing the imaginative and the conjecturing power, and then contemplates them, and finds them to have participated in some forms and to have differed in some other forms; and finds some amongst the forms that are in these powers to be essential and others to be accidental." (Avicenna Latinus [Ibn Sina])
"If you want to understand suffering you must look into the situation at hand. The teachings say that wherever a problem arises it must be settled right there. Where suffering lies is right where non-suffering will arise, it ceases at the place where it arises. If suffering arises you must contemplate right there, you don't have to run away. You should settle the issue right there. One who runs away from suffering out of fear is the most foolish person of all. He will simply increases his stupidity endlessly." (Ajahn Chah)
“In order to improve the mind, we ought less to learn, than to contemplate.” (Rene Descartes)
"In order to meditate, it is very important to first identify what we are meditating on. If we meditate without identifying that, there is the danger it will become idiot meditation or idiot Dharma. If we do not first fully comprehend through listening and contemplating the meaning of what we are meditating on, how can we practice?" (Gyalwa Karmapa)
"In the Martial Arts, introspection begets wisdom. Always see contemplation on your actions as an opportunity to improve." (Mas Oyama) [motto]
"In the same way, if we are confronted with koan, we have to contemplate it in the same way. Such a time is not the time for zazen, but for koan only, and we have nothing to do with zazen as suggested by the saying that the virtuous woman does not serve two husbands, nor does the loyal retainer serve two lords. Thus, when we are supposed to act, all we have to do is to act. We have to act for all our lives. When our whole bodies act, there is no dualistic self in us. When there is no self, there is nothing which is in opposition to us. I do not doubt that the universe is one with the whole active self." (Toin)
"Prayer can assume very different forms, from quiet, blessed contemplation of God, in which eye meets eye in restful meditation, to deep sighs or sudden exclamations of wonder, joy, gratitude or adoration." (Ole Hallesby)
"The unknown, our own true nature, has the capacity to wake itself up when you start to fall in love with letting go of all the mental structures you hold onto. Contemplate this: there is no such thing as a true belief." (Adyashanti)
"There's no wisdom from a man without harmony, and without harmony there is no contemplation. Without contemplation there cannot be peace, and without peace there can be no joy..." (Bhagavad Gita)
"When a garden is used as a place to pause for thought, that is when a Zen garden comes to life. When you contemplate a garden like this it will form as lasting impression on your heart." (Muso Soseki)
"When you are engaged in some work or other, you become one with it. In the intervals of your work, you immediately resume your contemplation on the koan. For instance, when you are smoking by the fireside or doing something like that, you are considered to be in the intervals of your work. At such a time you are absorbed in the contemplation on the koan free from dualistic thoughts and imaginations. This is one example of kufu in movement." (Kawajiri Hogin, "Zazen no Shokei" [The Warning/Observation on Zazen])
