Soul, energy, love, essence, prana and god are synonyms for me.
Illusion only exists with the limitations of this earth. Once the soul is liberated and free of the body and this material world, rich or poor, high or low does not matter anymore.
Soul is energy, the life in someone, our basic element, which moves us and keeps us alive. When there is no love in a relationship, we say it is dead. When there is no business in a company we say it is dead. Whenever the basic element of something is gone, we call it dead. When our basic element is gone, we are dead. And our soul is our basic element.
Love is the soul of our soul. Without it, you can be alive, but your soul is dead. We need love, it is the essence of our essence.
