Q.: Has the body any value to Self?

M.:
Yes,
it is through the body’s help
that Self is realised.

Q.:
What about diet?

M.:
Food affects the mind,
makes it more satvic (alive, vibrant, rhythmic),
for the practice of any kind of yoga.

Vegetarianism is absolutely necessary.

Q.:
Could one receive spiritual illumination
whilst eating flesh foods?

M.:
Yes,
but abandon them gradually
and accustom yourself to satvic foods.

However,
once you have attained illumination
it will make less difference what you eat,
as on a great fire it is immaterial
what fuel is added.
