Viruses of consciousness, like computer viruses, infect the basic programs of life. They distort perceptions and emotions, distort motives, self-esteem and intentions, cause painful attachments and depressive states, lead to weakening of the intellect and memory, provoke mental illness, cause failures and disappointments.
