Energy as a FEED really bites!
All living things instinctively feed to survive. Instinct pushes us to seek what makes existence possible. Something similar happens at the psychological level. The mind is becoming accustomed to recognizing what works to survive at the physical level. Our present understanding of what is beneficial for survival at the mental level and emotional levels is still a relatively uncharted territory. The process of feeding requires a degree of energy from ourselves that engages the body, our thoughts and emotions.
