Paramis, other than common thought, are not only importand if one desires for Buddhahood, but act-ually necessary to be able to join the path, the Savakas as well.
Seen in ideal manners, at the stage of leaving home for a non-comeback, one has already gained the "paramis".
A very usefull collection, also pointing out that each single parami was taught as means for liberation, is found in the study guide "
The Ten Perfections by Venerable Thanissaro Mahathera.
My person wonders, because Bhante usually puts much effort in drawing sets back to the set of 37 or the Noble Eithfold Path, why he didn't here.
One looking at the 10 paramis observingly will soon and easy find the common known factors of the path again (here "just" mixed for both modes of livelihood, lay or ascetic).
Dana (generous action)
Sila (virtue)
Nekkhamma (renunciation)
Pañña (wisdom, discernment)
Viriya (energy, effort)
Khanti (patience)
Sacca (truthfulness)
Adhitthana (determination, resolution)
Metta (goodwill, loving-kindness)
Upekkha (equanimity)
Even if it comes to happen that one leaves home, yet not gained the stream, one would need to relay on this set of paramis to arrive in an area able to gain path. In any case the factors fit well to householders practice and reflect all right intention,
sammāsaṅkappo or one not having gained path yet.
Whether finding the right Dhamma, the Sangha, heading to meet a Buddha, Arahatship, is all based on those pre-trainings, perfections, forms the condition for one to enter the path.
Gati (becoming, wander on) on that set is surely a save bet, wouldn't lead to
agati or development of grave wrong views.
Having re-ordered the set:
I. Discernment
Good Will (= right view, right resolve)
II. Truth
Virtue
Persistence (better placed under III, Samadhi, =effort)
III. Relinquishment
Generosity
Renunciation
IV. Calm
Endurance
Equanimity
One possible sees the 3 sections of the Eithfold path, wisdom (I), Virtue (II), Samadhi (III, IV).
