What is the human body? It is the apparatus by which the spirit incarnates and can have experiences, which on a spiritual plane we would be talking about eternities. So a minute on the material plane can equate to eternity on a spiritual plane.
So, we should take advantage of these experiences on the material plane, because it is the possibility of the evolution of the spirit within this experience that God created for us, so that we can reach this Christ consciousness. And we just have to practice, and we have the example - which is Jesus Christ - He showed us that through Love on this plane, He can overcome all the vicissitudes of life. Which is the instinctive part, which is the selfishness part, which is the anger, the emotions, all of this we can experience in the human body, to be able to overcome and to be able to evolve and transcend and reach spiritual understanding within this physical device.
That this is the main objective of this experience.
