पूर्णमदः पूर्णमिदंपूर्णात्पूर्णमुदच्यते ।पूर्णस्य पूर्णमादायपूर्णमेवावशिष्यते ॥
In plain words
That is whole. This is whole. Wholeness comes forth from wholeness. Take wholeness from wholeness, and only wholeness remains.
Close to the Sanskrit
That is full; this is full. From that fullness, this fullness arises. Taking fullness from fullness, fullness alone remains.
