Well, explain it please.
You don’t imagine that there is living energy within each of the rice kernels that you eat. Consuming a living thing is a transference of energy.
We do tend to see rice as something without life.
Your eyes see no movement so you see no life. If you could see with spiritual glasses, you would be amazed. Mental energy is a force from within the physical. Surely, physical energy does exist, but is rather different in scope than spiritual energy. The physical is limited, but spiritual is not.
