Under Cover

“Mendicants, three things are conveyed under cover, not in the open.
What three?
Females are married with a veil, not unveiled.
Brahmin hymns are conveyed under cover, not openly.
Wrong view is conveyed under cover, not in the open.
These three things are conveyed under cover, not in the open.
Three things shine in the open, not under cover.
What three?
The moon shines in the open, not under cover.
The sun shines in the open, not under cover.
The teaching and training proclaimed by a Realized One shine in the open, not under cover.
These three things shine in the open, not under cover.”
