Entering the Noble Stream leading to Nibbâna:
At Savatthi the
Buddha said:
Bhikkhus, the eyes are impermanent,
changing, becoming otherwise. All forms
are impermanent, changing,
& becoming otherwise. The ear & all sounds, the nose & all smells,
the tongue & all tastes, the body, all touches, & the mind & all ideas
are
all impermanent, transient, changing, and becoming otherwise...
One who accepts these teachings by
understanding, after having
examined them, by careful reflection, is called a
Dhamma-follower!
One who decides to place confidence in these teachings, is called
a Faith-follower! Both such persons have entered the fixed track
of correctness, entered a plane of superior being, & transcended
the level of ordinary worldling. Such beings cannot do any action
later resulting in rebirth in hell, or as animal, or as hungry ghost!!!
Such
Nobles are incapable of dying without first having enjoyed
the fruit of
stream-entry. Knowing & seeing these teachings thus,
one is called a
Stream-Enterer, saved from lower worlds, fixed in
destiny, with enlightenment as destination within 7 lives at most...!!!

SUPREME SAFETY
In comparison with kingship over whole earth,
In comparison with arising in a divine world,
In comparison with supremacy over all universes,
the fruit of entering the Stream - being a
Sotāpanna
-
is of supreme excellence.
