This again follows a cyclic pattern. This evolution achieves experience, self-awareness, and ever increasing perfection. Evolution occurs on the physical, mental, and spiritual planes. The origin of the species is due to intelligent design. There is a seven fold constitution of man ranging from the physical plane to the purely spiritual plane.
Thoughts are tangible objects on higher planes.
Every thought and action has its effect on us and on our surroundings and has a karmic consequence. At the moment of death we have a review of our life just past - as we cast off this physical frame. After a short period, that varies greatly between individuals, we cast off other lower aspects of our constitution and the reincarnating self begins a long period of merciful, earned, rest before the next birth. Often during this life, our spiritual nature is obscured in our self-centered daily lives as we cater to our immediate needs and desires. But the spiritual self is always there to guide us if we seek it with strong earnest desire.
