Om Purnamadah Purnamidam
Om shanti, shanti, shanti
Meaning of Om Purnamadah
This is perfect, that is perfect.
The perfect emerges out of the perfect.
Even after taking the perfect out of the perfect, that which remains is still perfect.
Om, Peace, Peace, Peace.
God is perfect and complete, and because He is completely perfect, all emanations from Him, such as this phenomenal world, are perfectly equipped as complete wholes. Whatever is produced of the complete whole is also complete in itself. Because He is the complete whole, even though so many complete units emanate from Him, He remains the complete balance.
- Isha Upanishad
