The Blessed Buddha once said:
In so far as there are beings
without feet, with two feet or with four feet,
or with many feet, with form or formless, conscious or unconscious, or
even
neither-conscious-nor-unconscious, of all these the Tathagata is the highest,
the most worthy Arahat, the supreme Perfectly Self-Awakened One...
Whoever has faith in the Buddha, has
therefore faith in what is truly highest!
For those who have faith in this
sublime highest, the highest is also the result...
In so far as there are conditioned states, the Noble 8-fold Way is
the highest.
Whoever has faith in this noble 8-fold Way, has faith in what is
truly highest!
For those who have faith in the highest, the highest will
logically be the result.
In so far as there are mental states, whether constructed or unconstructed,
dispassion, stilling, ceasing is truly the highest of these states, that is Nibbana...
Whoever has faith in this supreme subtle state, has thus faith in what is highest!
For those who have faith in the highest, the highest will be the resulting
effect...
In so far as there are communities, companies and groups, the community of the
Disciples of the Buddha - The Sangha - is truly the highest of these,
since it is
an unsurpassed Field of Merit. Whoever has faith in the Sangha, has faith in
what is highest! Those who have faith in the highest, will experience the highest...
