The 4 stepping stones to entering the Stream Supreme!

Once in Savatthi the Blessed Buddha said this:
Bhikkhus, there are these four factors of Stream-Entry.  What four?
1: Association with excellent persons, is a stepping-stone for Stream-Entry.
2: Hearing the true Dhamma is a stepping-stone for Stream-Entry.
3: Careful and rational attention is a stepping-stone for Stream-Entry.
4: Praxis in agreement with the Dhamma is a stepping-stone for Stream-Entry.
These 4 factors of Stream-Entry does any Noble Disciple possess!!!

OBS: The Stream Winner!
A Stream-Enterer (Sotāpanna) has maximum 7 lives left before Enlightenment!
He/she cannot be reborn in hell, as a ghost, as an animal, nor as an angry demon,
and is thereby safe from the danger of kammic downfall! Further details see:
