Loneliness expresses the pain of being alone and solitude expresses the glory of being alone.

We're born alone, we live alone, we die alone. Only through our love and friendship can we create the illusion for the moment that we're not alone.
I care for myself. The more solitary, the more friendless, the more unsustained I am, the more I will respect myself.
There is a fellowship more quiet even than solitude, and which, rightly understood, is solitude made perfect.

Solitude is a silent storm that breaks down all our dead branches; yet it sends our living roots deeper into the living heart of the living earth.
I live in that solitude which is painful in youth, but delicious in the years of maturity.
