simple guidelines for aspirants and disciples:
is impossible for the loftier currents of thought to impact the little evolved physical brain.
the refinement of the physical body is an essential. It is effected in various ways, all of them reasonable and utilitarian.
pure food. This involves a vegetarian diet, chosen with wise discrimination; it requires the eating of only those vegetables
and fruits that vitalize.
judgment shown in the choice of food, wise refraining from too heavy eating, and a little pure good food perfectly assimilated
are all that a disciple requires.
ask what foods?
the vegetables that contact the sun,
(above all, oranges), [A vegetarian diet is beneficial, especially
oranges. FW3 536.]
Rice, and may I again reiterate, just as much of all the above as to insure activity.
cleanliness. Much use of water, externally and internally, is vitally required.
sleep. This should be always between the hours of ten in the evening and five in the morning, and as much as possible out
sunshine. Contact with the sun should be much sought after, and the vitalization that comes through its rays. The sun kills
all germs and frees from disease.
these four requirements are attended to adequately a definite process of elimination proceeds, and in the course of a few
years the whole physical body shifts its polarization gradually up until ultimately you will have a body composed of atomic
subplane matter... This may take several incarnations, but it should be borne in mind that at each fresh incarnation a body
is taken of the exact quality (if I may so put it) as the one previously discarded at death. Hence time is never lost in building.
