How do I ensure my child is healthy?

As a general thing, we do not realise that by neglecting or abusing the material body we are sinning against the spirit, for the spirit depends solely upon this material body for sustenance and strength. 

Much can be added and a great deal taken away by a neglect of this law. Bright intellect can be developed—mind can be cultivated if the material body performs its natural functions. No one should under any consideration neglect the material body—every condition necessary to its growth, health and strength should be complied with. This should be the first lesson taught to the child and firmly impressed upon his or her mind as a religious duty, for without the material there can be no advance of the spiritual, and without the spiritual the material would perish, for it would have no life.

—B. H. in Spirit
