Quotes about Nirvana

The Buddha's insight into the middle way is not simply about a balance between extremes. This conventional understanding misses the deeper revelation of the middle way as being the very nature of unexcelled enlightenment. The middle way is an invitation to leap beyond nirvana and samsara and to realize the unborn Buddha mind right in the middle of everywhere.

There is no meditation without wisdom, and there is no wisdom without meditation. When a man has both meditation and wisdom, he is indeed close to nirvana.

Nirvana means to extinguish the burning fires of the Three Poisons: greed, anger, and ignorance. This can be accomplished by letting go of dissatisfaction.

If you want to know something, go elsewhere. If you want to un-know everything, then sit and listen.

"Enlightenment" and "Nirvana"?
They are dead trees to fasten a donkey to.
The scriptures?
They are bits of paper to wipe mud from your face.
What can these things have to do with you becoming free?

The Buddha may open the door, but you must decide to walk through to the world of wisdom and enlightenment

As you learn to leave alone the activity of unconsciously trying to be the mindbody that you think that you are - the mindbody that this "you" is currently flowing through - and you learn to move as this one that you truly are - this "you" of you; the very heart of existence - steadily, consciously and momentarily, the continuity of the ever deepening of this innermost as it keeps on entering its manifestation, through this mindbody that you find yourself flowing through, allows you to simply bubble in the sheer joy, pleasure, peace, delightfulness and stillness that this "you" of you is.

In the light of consciousness all sorts of things happen and one need not give special importance to any. The sight of a flower is as marvelous as the vision of God. Let them be. Why remember them and then make memory into a problem? Be bland about them; do not divide them into high and low, inner and outer, lasting and transient. Go beyond, go back to the source, go to the self that is the same whatever happens. Your weakness is due to your conviction that you were born into the world. In reality the world is ever recreated in you and by you. See everything as emanating from the light which is the source of your own being.   - Nisargadatta

The intricacies of spiritual philosophy and theologies are just a thought within Emptiness.

Nirvana is an experience of the Unconditioned which defies any description.  Any description of Nirvana is not a description of Nirvana, and that is the most that can be said about Nirvana.  There are no reference points in Nirvana on which to base a description.

If you touch the phenomenal realm deeply, you touch the ultimate realm which is the realm of no birth and no death.  The ultimate is nirvana, it is God, and it is available to us twenty four hours a day.

Zorba the Buddha
...I really don't know from which Book of Bhagwan/Osho I caught the quote, but he used it frequently and I'm pretty sure it's a well known quote...

"Does one really to fret about enlightenment?  No matter what road I travel, I'm going home."

Inflowing thoughts come to an end in those who are ever alert of mind, training themselves night and day, and ever intent on nirvana

I have passed in ignorance through a cycle of many rebirths, seeking the builder of the house. Continuous rebirth is a painful thing. But now, housebuilder, I have found you out. You will not build me a house again. All your rafters are broken, your ridge-pole shattered. My mind is free from active thought, and has made an end of craving.
