Meaning:
1: Om, That (Outer World) is Purna (Full with Divine Consciousness); This (Inner World) is also Purna (Full with Divine Consciousness); From Purna comes Purna (From the Fullness of Divine Consciousness the World is manifested) ,
2: Taking Purna from Purna, Purna Indeed Remains (Because Divine Consciousness is Non-Dual and Infinite).
3: Om Peace, Peace, Peace.
