"What are the principal factors that can be complied with in order to build a strong healthy vital body? Is it possible for a person with a rather weak vital body to strengthen it? May not a so-called weak vital body be a healthy one at the same time, the weakness manifesting in non-staying power and a slowness in recovery from fatigue?"

This question is concise and can be briefly answered. In fact it must be, or otherwise a long discussion will be necessary upon the subject of the vital body, and that is too vast a one with which to deal here, and the implications are too many. I have given you much in the various books I have written.

When you say a weak vital body I presume you mean one which is loosely coordinated with the physical vehicle and loosely connected, and which has therefore a weak hold upon the outer form, for it is the close integration of the etheric body with the physical form which is the cause of all its staying power. You are right in your belief that one can be perfectly healthy but have little resistance to fatigue.

The principal factors in re-establishing or making a better etheric control are:

1. Sunshine.
2. Careful diet, with the emphasis upon the proteins and vitamins.
3. The avoidance of fatigue and worry. [327]

Against all the above, at this time, climate, world conditions, environment and our civilization militate, and the individual has therefore to resign himself to a state of affairs which lies outside his individual control.
