― 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
