Theology: the learning and developing of methods and practice in how to make people feel like shit about themselves, to make them scared of imaginary beings, also a method of middle man money extraction and a means to power and wealth filled with manipulative and needless speculation.
This madness is also tightly woven into religion, modern physics and political identity, and is both a curse and a source of endless wars, hatred and emotional abuse.
Spirituality: the day to day realization that there are things bigger than one's self, and that the huge and beautiful mystery known as life and sentience is bigger than our tiny primate brains could hold.
Being solidly connected to spiritual thinking in a world full of fundamentalist thinkers is a rare gift, and sensitive people who can rub more than a few neurons together are often driven mad by people practicing the often barbaric and ruthless methods of theology. Which have been all of them from where I see things.
