Truth is the state of being in accordance with reality.
Reality is the state of things as they actually exist.
Exist is to be real whether in material or spiritual.

The breath of my life is on the edge,
for I cannot define the truth any longer.
The words hear like babble in my ears,
since I cannot determine their actual reality.
The solidity of my skin is eroding,
because I cannot answer on the behalf of existence.
