The
Purpose of Purification
is Release!
Buddha explained that it is for the sake of Nibbāna
that one trains the mind:
Morality is for the sake of self-control, control for the sake of absence of
regret,
Absence of regrets is for the sake of joy, joy is for the for the sake of bliss,
Bliss is for the sake of tranquillity, tranquillity is for the sake of
happiness,
Happiness is for the sake of absorption into one-pointed concentration,
Concentration is for the sake of knowledge & vision of how reality comes to be,
Knowledge and vision of how reality comes into being is for the sake of disgust,
Disgust is for the sake of disillusion, dry disillusion is for the sake of
release,
Mental release is for the sake of knowledge and vision of awakening release,
Knowledge & vision of release is for the sake of
Nibbāna
without clinging!
For this purpose is this speech, for this purpose is this noble advice!
For this purpose should one pay attention to this chain of causes!
That is: For the purpose of release of mind through non-clinging...
