In any of the four times and ten directions enlightenment will not be found except in the mind, which is the fully enlightened state. Do not seek the Buddha in any other source. (Otherwise) even if the Buddha (himself) searches, it will not be found.
The only position from which you can never fall is the awakened state.
— Dilgo Khyentse Rinpoche
The true nature of beings is always buddha. Not realising that, they wander in endless samsara. For the boundless suffering of sentient beings, may unbearable compassion be conceived in our being.
— 3rd Karmapa Rangjung Dorje
To insist on a spiritual practice that served you in the past is to carry the raft on your back after you have crossed the river.
I reached in experience the nirvana which is unborn, unrivaled, secure from attachment, undecaying and unstained. This condition is indeed reached by me which is deep, difficult to see, difficult to understand, tranquil, excellent, beyond the reach of mere logic, subtle, and to be realized only by the wise.
