“When we decide to perform an action, the gandhabba sends a signal to the mana indriya in the brain in the form of kirana (ray system). “
- Yes. This is an “internal communication system” based on kammic energy. It uses energy imparted to the human gandhabba when it was created by kammic energy.
“This causes an electrical activity in the brain which will then use the energy that came from food to send this signal to other parts of the body by converting them to suitable electrochemical energies.”
- Yes. Scientists are studying this. However, they think decisions about moving body parts originate in the brain. They say a combination of electrical and chemical signaling systems operates. They say about 25% of the energy generated by food we eat is consumed by the brain.
“So conveniently, it should be fine to say there is a mental energy that comes from the gandhabba after deciding, which is then converted to other forms of energy. This is acceptable as long as we are mindful of the fact that this is not necessarily the kammic energy generated by javana citta that can create kamma vipaka in the future.”
- I am not sure what you mean by that. Please elaborate on that.
“Cittas arise and fade away. So it is understandable that there has to be some form of energy causing this.”
- Cittas arise and fade away as long as the gandhabba has enough kammic energy left over. At the end of its life (many thousands of years), gandhabba dies, and the citta generation stops. But during the last citta vithi, a new gandhabba or a lifeform (human, animal, Deva, Brahma, etc) is created using another “packet of kammic energy that had been accumulating in vinnana dhatu.”
- Any given lifestream has generated many such “packets of kammic energy” that can potentially create existences in various realms. The strongest one in line takes priority/precedence. This is how the rebirth process continues seamlessly.
- Ask questions on this last part also if it is not clear.
