They’re addicted to heedlessness
—dullards, fools—
while one who is wise
cherishes heedfulness
as his highest wealth.
-Dhammapada

This mind is like a fish out of water that thrashes and throws itself about, its thoughts following each of its cravings.
Such a wandering mind is weak and unsteady, attracted here, there and everywhere. How good it is to control it and know the happiness of freedom.
-Dhammapada

There are two kinds of suffering: the suffering that leads to more suffering and the suffering that leads to the end of suffering. If you are not willing to face the second kind of suffering, you will surely continue to experience the first.
-Ajahn Chah, “Still Forest Pool”

Passion is the cause of blindness, of not seeing, of not knowing, of loss of insight: it is joined with vexation, it does not conduce to Nibbana.
-Anguttara Nikaya

Just like a blossom,
bright coloured and full of scent:
a well-spoken word is fruitful
when well carried out.
-Dhammapada

As a mother, at the risk of her life,
Watches over her only child,
Let him cherish an unbounded mind
For all living beings.
Let him have love for the whole world,
And develop an unbounded mind,
Above, below and all around,
Boundless heart of goodwill, free of hatred,
Standing, walking, sitting or lying down,
So long as he be awake,
Let him cherish this thought,
This is called divine abiding here.

-Karaniyametta Sutta

The brightly shining mind is never absent but is coloured by the thoughts and emotions that people put upon it. If you were to see the luminous freedom of this mind, you would cultivate it before any other, keeping it free from all attachments.
-Anguttara Nikaya

You should roam in places that are your own, that arise in accordance with your own true nature.
And what is the place that is your own? It’s the pasture of ardent clearness and mindfulness, where discontent and greed are put aside for the sake of the world. That is your own place, your natural range.
-Samyutta Nikaya

A person of wisdom should be truthful, without arrogance, without deceit, not slanderous and not hateful. The wise person should go beyond the evil of greed and miserliness.
Do not get excited by what is old, do not be contented with what is new. Do not grieve for what is lost or be controlled by desire.
-Sutta-nipata

See it as a bubble, See it as a mirage; One who regards the world this way the King of Death doesn’t see. Come, look at this world all decked out like a royal chariot, where fools plunge in, while those who know don’t cling.
-Dhammapada
