OM! That (the Invisible–Absolute) is whole; whole is this (the visible phenomenal); from the Invisible Whole comes forth the visible whole. Though the visible whole has come out from that Invisible Whole, yet the Whole remains unaltered. OM! PEACE! PEACE! PEACE
If you have studied higher secondary maths, you can easily understand this.
The God is infinite !
This property was known to us (Bharatiyas) long long ago........
Glory of Bharat can not delivered in words !
OM is INFINITY (or Absolute everything that is countless and beyond the scope of our imagination)
Everything that we can see, feel, smell, hear, etc in this world, is the product of this OM.
Even if you think, everything that this world has today is beyond ones calculation or for example is at infinity, even then, the source "OM" stays what it was Absolute Everything i.e. INFINITY.
For E.g. Infinity - Infinity = Infinity
