The Twin Truths won by keen Dual Consideration:
The blessed Buddha once said:
Friends, the first consideration is:
Whatever Misery arises, this Misery is caused by Acquisition!
Another consequent & subsequent consideration is:
Stopping all Acquisition of Fuel, stops all arising of Misery!
Taking up many acquisitions, clinging to possessions & thereby accumulating
fuel for renewed becoming, the fool comes to Misery ever again & again!
Letting go, renouncing, & leaving all behind, the wise goes scot free at ease!
Considering these twin truths cautiously, resolutely & enthusiastically, one
may either enter the state of Nibbāna right here & now in this very life,
or if there is remaining traces of Clinging , the state of non-return...
Those who neglect understanding Clinging, origin of Clinging, End of Clinging,
and how Clinging is completely & irreversibly eliminated, are incapable of
release by understanding, are incapable of mental release, are incapable
of direct knowledge, and thereby become incapable of making an end...
They repeat birth, ageing, decay, sickness & death ever again & again...
While those who undertake understanding of Clinging, Origin, End & Way,
are indeed capable of mental release by understanding, direct knowledge,
and thus capable of making an end... They are headed towards the deathless!

Any Acquisition is Accumulation of Suffering!
