― Freedom from regret, Ananda.
― And what is the advantage of freedom from regret?
― Joy that produces bliss, Ananda.
Bliss then generates happiness;
Happiness enables concentration;
Concentration facilitates vision and knowledge;
Vision and knowledge bring disillusion and detachment;
And Disillusion and detachment induce direct experience
Of certain and complete mental release.
Buddha Shakyamuni, Anguttara Agama
