BUDDHIST QUOTES ON MIND

“If you want to understand all the Buddhas of the past, present and future,
then you should view the nature of the whole universe, as being created by Mind-only…” 

Avatamsaka sutra

“Who, then, is “animate” and who “inanimate”? Within the assembly of the Lotus, all are present without division. In the case of grass, trees and the soil…whether they merely lift their feet or energetically traverse the long path, they will all reach Nirvana.”

^{Tiantai patriarch Zhanran} 

“The Dharmakaya is nothing other than the physical universe and natural objects like rocks and stones are included as part of the supreme embodiment of the Buddha.”
9th-century Shingon Buddhist Philospher Kukai

“All the Buddhas and all sentient beings are nothing but the One Mind, beside which nothing exists. This Mind, which is without beginning, is unborn and indestructible. It is not green nor yellow, and has neither form nor appearance. It does not belong to the categories of things which exist or do not exist, nor can it be thought of in terms of new or old. It is neither long nor short, big nor small, for it transcends all limits, measure, names, traces and comparisons. It is that which you see before you – begin to reason about it and you at once fall into error. It is like the boundless void which cannot be fathomed or measured. The One Mind alone is the Buddha, and there is no distinction between the Buddha and sentient things, but that sentient beings are attached to forms and so seek externally for Buddhahood. By their very seeking they lose it, for that is using the Buddha to seek for the Buddha and using mind to grasp Mind. Even though they do their utmost for a full aeon, they will not be able to attain it. They do not know that, if they put a stop to conceptual thought and forget their anxiety, the Buddha will appear before them, for this Mind is the Buddha and the Buddha is all living beings. It is not the less for being manifested in ordinary beings, nor is it greater for being manifest in the Buddhas.”
Huangbo Xiyun

“Luminous, monks, is the mind. And it is defiled by incoming defilements.” 
Anguttara Nikaya (A.I.8-10)v –  the discourses indicate that the mind’s natural radiance can be made manifest by meditation..
