[Advaita-l] Sloka :: Soma Yaga

[Krishnan S]

Dear Scholars,

I came across this sloka at the invitation of a certain Soma Yaga.  ( This
couplet, I have the Tamil version , thus there
may be some typos)

चतुर्भिश्च चतुर्भिश्च  द्वाभ्यां पञ्चभिरेव च।
हूयदेश पुणर्द्वाभ्यां स् नो विष्णु प्रसीतदु॥

1. What is the meaning of this sloka?
2. What is its source?

Thanks
Krishnan
