What is an energized spirit? This relates to your WILL to live. How badly do you want to get up in the morning? Do you jump out of bet fueled on passion or do you slowly and hesitantly rise from your coffin?
The WILL of an individual has plenty to do with the story they choose to believe to be true, connecting to their reality. As consciousness grows to higher levels, the WILL of an individual enlarges.
Where doe this energy increase come from? It comes from an idea inside of you, charging you up and making it a real effort to stop yourself from moving. Those with the most energy are those who believe that what they are doing will actualize the ideas formed in the mind. Those suffering from low energy levels are trapped in states of ignorant obliviousness.
When a couple is married for a whole lifetime, it is often the case that when one departs, the other WILLs not to continue on alone and leaves this world, as well.
