By crucifying oneself to the world, and the world to oneself (Gal. 6:14)}, brethren, our souls therefore die before death and rise again before the resurrection of the body in deed, in power, in experience, and in truth. When the mortal attitude has been eliminated by the immortal mind and mortality has been driven out by life, then, as though it had risen from the dead, the soul manifestly sees itself, just as those who rise from sleep see themselves. It recognizes God who has raised it; as it perceives Him it gives Him thanks and worships Him and glorifies His infinite goodness. On the other hand, the body is entirely without breath, motion, and memory in relation to its own desires, but in these respects becomes altogether dead and lifeless.

(Saint Symeon the New Theologian)
