a. “O monks, the well-instructed noble disciple, seeing thus, gets wearied of form, gets wearied of feeling, gets wearied of perception, gets wearied of mental formations, gets wearied of consciousness. Being wearied he becomes passion-free. In his freedom from passion, he is emancipated. Being emancipated, there is the knowledge that he is emancipated. He knows: 'birth is exhausted, lived is the holy life, what had to be done is done, there is nothing more of this becoming.'” - Buddha in Anatta-lakkhana Sutta: The Discourse on the Not-self Characteristic
b. “Any kind of consciousness whatever, whether past, future or presently arisen, whether gross or subtle, whether in oneself or external, whether inferior or superior, whether far or near must, with right understanding how it is, be regarded thus: 'This is not mine, this is not I, this is not my self.'” -Anatta-lakkhana Sutta: The Discourse on the Not-self Characteristic
c. "The five skandhas represent the constant structure of the human psychology as well as its pattern of evolution and the pattern of the evolution of the world. The skandhas are also related to blockages of different types — spiritual ones, material ones, and emotional ones." - Chögyam Trungpa Rinpoche
d. “Once we have a physical body, we also have what are known as the five skandhas — the aggregates that compose our whole mental and physical existence. They are the constituents of our experience, the support for the grasping of ego, and also the basis for the suffering of samsara.” - Sogyal Rinpoche
e. "The five skandhas represent the constant structure of the human psychology as well as its pattern of evolution and the pattern of the evolution of the world. The skandhas are also related to blockages of different types — spiritual ones, material ones, and emotional ones." - Chögyam Trungpa Rinpoche
f. “Mind precedes all mental states. Mind is their chief; they are all mindwrought. If with an impure mind a person speaks or acts suffering follows him like the wheel that follows the foot of the ox. Mind precedes all mental states. Mind is their chief; they are all mind-wrought. If with a pure mind a person speaks or acts happiness follows him like his never-departing shadow.” -Dharmmapada
