After Mass during prayer, I became aware of the following.
God has created this physical universe, but he lives in the spiritual world. We have our physical body here, but our soul is not to live forever in this physical world. We are very much aware of the body ~ its weight, the pains and aches, the tiredness, etc. Even when I pray, I am conscious of the discomfort of the body, distracting me from my concentration. The body basically is a drag, but we just have to live with it.
Then I intuitively see that the soul is a separate entity. The soul has a life of its own, you might say. The body and the soul have different demands, each operating in its own world. In this life, they are merged in one person, but they are so distinct from each other that I see clearly that the soul's home is not in this world. The body is designed to dwell in this physical universe temporarily and the soul to dwell in the spiritual world for all eternity with God, just as Jesus came into the world and then ascended into heaven.
This awareness helps me become even more detached to this world.
