The brain is nourished by reaction and experience; it lives on experience. But experience is always limiting and conditioning; memory is the machinery of action. Without experience, knowledge and memory, action is not possible but such action is fragmentary, limited. Reason, organized thought, is always incomplete; idea, response of thought, is barren and belief is the refuge of thought. All experience only strengthens thought negatively or positively.
Experiencing is conditioned by experience, the past. Freedom is the emptying of the mind of experience. When the brain ceases to nourish itself through experience, memory and thought, when it dies to experiencing, then its activity is not self-centred. It then has its nourishment from elsewhere. It is this nourishment that makes the mind religious.
