One becomes Calmed by Stilling all Agitation!...

The brahmin Māgandiya asked the Buddha about how to become calmed:
Not dwelling in the past, stilled in the present, one prefers no kind of future!
Without irritation, without agitation, without regrets, without worry, neither
boasting, nor proud, but humble and modest, one is indeed a restrained sage...
Withdrawn, not opposed to anything, not wanting anything, all unconcerned,
aloof, gentle, independent, for such one there exists neither craving or fear
for any kind of existence, nor craving or fear for any form of non-existence...
Such calmed one is indifferent to sense pleasures, detached, not clinging to
any kind of property! For him there is nothing more to take up or lay down!
For whatever others might accuse him, he remains tranquil and not agitated!
Neither opposed to anything, nor attracted to anything, with nothing of his
own, not perturbed by what does not exist, such tranquil one is truly calmed!
