All formations are transient; all formations are subject to suffering; all things are without a self.

Therefore, whatever there be of form, of feeling, perception, mental formations, or consciousness, whether past, present, or future, one’s own or external, gross or subtle, lofty or low, far or near, one should understand according to reality and true wisdom: ‘This does not belong to me; this am I not; this is not my Self.’
- Anguttara Nikaya and Samyutta Nikaya

A sage does not speak in terms of being equal, lower or higher. Calmed and without selfishness he neither grasps nor rejects.
- Sutta Nipata

What, monks, is totality? It is just the eye with the objects of sight, the ear with the objects of hearing, the nose with the objects of smell, the body with the objects of touch and the mind with the objects of cognition. This, monks, is called totality.
- Samyutta Nikaya

Just like a blossom,
bright coloured
but scentless:
a well-spoken word
is fruitless
when not carried out.
- Dhammapada [4]

That’s not a strong bond
–so say the enlightened–
the one made of iron, of wood, or of grass.
To be smitten, enthralled,
with jewels & ornaments,
longing for children & wives:
that’s the strong bond,
–so say the enlightened–
one that’s constraining,
elastic,
hard to untie.
But having cut it, they
–the enlightened–go forth,
free of longing, abandoning
sensual ease.
-Dhammapada [24]

‘There is no spot, O king, where Nirvâna is situate, and yet Nirvâna is, and he who orders his life right will, by careful attention, realize Nirvâna. Just as fire exists, and yet there is no place where fire (by itself) is stored up. But if a man rubs two sticks together the fire comes; just so, O king, Nirvâna exists, though there is no spot where it is stored up. And he who orders his life aright will, by careful attention, realize Nirvâna.
- Milindapanha

The world’s end can never be reached
by means of travelling through the world,
Yet without reaching the world’s end
there is no release from suffering.

Therefore, truly, the world-knower, the wise one,
gone to the world’s end, fulfiller of the holy life,
having known the world’s end, at peace,
longs not for this world or another.
- Buddha

They, the enlightened, intent on jhana,
delighting in stilling
& renunciation,
self-awakened & mindful:
even the devas
view them with envy.
-Dhammapada [14]

Blinded this world—
how few see clearly!
Just as birds who’ve escaped
from a net are few,
few are the people
who make it to heaven.
- Dhammapada [13]

The Lord taught a holy life
Not based on tradition,
For restraint and abandoning,
Leading to and merging in Nibbana.

This is the path followed by the great,
Pursued by the lofty sages.
Those who enter that course
As taught by the Enlightened One,
Heeding the Teacher’s instruction,
Will make an end of suffering.
- Itivuttaka
