The Blessed Buddha once said:
The habitual praxis of the observance day endowed with eight
features brings high reward and blessing, & is of sublime dignity
and greatness. And which are these eight features? In this, any
Noble Disciple considers within himself: Throughout their life the
Arahats avoid sexual intercourse, dwelling celibate, abiding aloof,
far above copulation and masturbation, vulgar animal-like praxis...
May also I, this day and night,
avoid copulation and masturbation...
By that I will follow the track & traits of the perfected Arahats!
I shall then have observed the Uposatha observance day perfectly.
With this third praxis is the observance day enriched. Observed
this very way, the observance day endowed with eight features
brings high - even divine - reward & blessing & is of sublime dignity
and immense greatness...
