Following lines always inspire me:

” Om PurNamadah pUrNamidam
pUrNAt pUrNamudachyate
pUrNasya pUrNamAdAya
pUrNamevAvashiShyate
Om shAntih, shAntih, shAntihi ! “

“This is Whole.

 That is Whole.

 Whole emerges from Whole.

 Whole subtracted from Whole results in Whole.”

The notion of zero arises from the revolutions of the planets. It is the symbol of all the returns,all the cycles,all the rythems,that make existence possile. It also represents the limit between different orders of existence and the origin of manifestation; an instant when a thing does not yet exist and yet has already begun.

completeness alone remains
