The thought, "The body is a physical manifestation of the soul", can also be expressed as "The body tangibleizes the soul".
Examples of things which "tangibleize" an invisible thing—such as a thought—are words, drawings, photographs, images, and sculptures or
3-D models because those things have transformed a thought or feeling into a visible or
tangible representation of them.
And though spoken words manifest thoughts, no one can see a
spoken word. To make a word visible, it must be written or typed. Then it can be moved around in a text. Though it is not possible to touch or hold written word
per se, they can be said to be tangible because when written, they can be sent in a letter or email, or when printed on a paper or in a book, carried.
