Does the evolution of the individual begin with his earthly appearance?

Does the evolution of the individual begin with his earthly appearance?

While self-radiant and capable of wonderful development, the individual soul is still a part of the divinity. Each man is not God and yet each soul contains a particle of the divine essence, divinely implanted.

To reach the centre of light and its perfection, each individual progresses through many evolutions, each one permitting a fuller measure of light. Each evolution has its duties and tasks to perform, its education to make and its errors to overcome. These are not existent; they are the natural outcome of liberty, free will and limited understanding of the imperfect individual. Naturally, they differ in each plane, but the nearer we come to the fount of wisdom, the stronger we are and the greater is our happiness, for we see more clearly the meaning of life and its glorious possibilities.
