The blessed Buddha once said:
Friends, the first consideration is: Whatever Misery arises, all does so caused by Contact !
Another consequent consideration is: By stopping Contact, there cannot ever arise any Misery !
The fool immerses himself in Contact & suffers thereby, when it fades.
The wise by comprehending this inherent danger in any Contact withdraw,
by quenching his urge for contacting ever changing imprints of sensation...
Considering these twin truths cautiously, resolutely & enthusiastically,
one may either enter the state of Nibbāna right here & now in this life,
or if there is lasting traces of clinging left, the state of a non-returner...
Those who neglect understanding Contact, the origin of Contact, the End
of Contact, & how Contact is completely eliminated, are thus incapable of
release by understanding, are thus incapable of mental release, are thus
incapable of direct knowledge, and are thus incapable of making an end...
They repeat birth, ageing, decay, sickness & death ever again...
While those who undertake understanding of Contact, Origin, End & Way,
are quite capable of mental release by understanding, & capable of making
an end... They are near the deathless dimension!
