What is an intellectual mind?

If the physical body is carefully nourished, the spiritual faculties can work through its organs, assisting its development through its experiences and various unfoldments, which are essential to its strength and development. When the spirit attains its development through experience, it unfolds the intellect, which the spirit requires, so that it may attain its individuality. Experience in this material life aids the spirit to progress by being informed of natural facts and unfolding its identity to the great God-principle. Very few minds have a conception of how small the first expression thrown off from Deity is. It is but a thought devoid of shape or form―an intellectual thought.
