In the mathematical sense, in the worldly sense, when a part is disassociated from the whole, then something reduces from the whole.
In the existential sense, the whole remains whole even after manifesting all the parts.
The whole has an infinite potency to express even more parts after all the parts have been expressed.
Even in absence of all the parts, the whole is still there.
Even in the presence of all the parts, actually the parts are not present; only the whole is present.
