What is a spiritual body?

Our birth is but a sleep and a forgetting—

The soul that rises with us, our life’s star,

Hath had elsewhere its setting,

And cometh from afar—

Not in entire forgetfulness,

And not in utter nakedness,

But trailing clouds of glory do we come

To God, who is our home.

—William Wordsworth, Ode, Intimations of Immortality

Our birth into spirit life differs in almost every point from our birth into the earthly. We owe our earthly body to others—our psychic body to ourselves. That is—the state of development in which we arrive in the world of spirits depends greatly on our past life and we may be said to be born in the spirit world as infants, children or mature beings, according to the past life and the present state of the true self.

Our psychic body is being formed within the earthly during our earthly life, but the materials of which it is composed are not earthly, but are finer, rarer, though still material and capable of outward manifestation to the psychic vision.
