By material vital we mean the vital so involved in Matter as to be bound by its movements and gross physical character; the action is to support and energise the body and keep in it the capacity of life, growth, movement, etc., also of sensitiveness to outside impacts.

I would like to know what You mean by "the most material vital".
It is the part of the vital that is closest to the physical consciousness, the part that gives life to the body.

There is a whole zone in the most material vital which penetrates, as it were, the subtle physical - that's where illnesses are formed. You see swarms of completely crooked formations - a lack of sincerity. And it expresses itself in images: I see all kinds of people and do all kinds of things in a special zone - the same people who are elsewhere are here too under a special aspect. It's a mixture of the deformation of consciousness, the deformation of language, the deformation of forms - swarms and swarms!

You carry with you, around you, in you, the atmosphere created by your actions, and if what you do is beautiful, good and harmonious, your atmosphere is beautiful, good and harmonious; on the other hand, if you live in a sordid selfishness, unscrupulous self-interest, ruthless bad will, that is what you will breathe every moment of your life and that means misery, constant uneasiness; it means ugliness that despairs of its own ugliness.
And you must not believe that by leaving the body you will free yourself of this atmosphere; on the contrary, the body is a kind of a veil of unconsciousness which diminishes the intensity of the suffering. If you are without the protection of the body in the most material vital life, the suffering becomes much more acute and you no longer have the opportunity to change what is to be changed, to correct what is to be corrected, to open yourself to a higher, happier and more luminous life and consciousness.
You must make haste to do your work here, for it is here that you can truly do it.
Expect nothing from death. Life is your salvation.

As a rule, I mean in their unchanged condition, the lower parts get interested and enthusiastic when the ego mixes with the interest. But the pure enthusiasm can come into them as they get more and more converted and purified and they then become very indispensable forces for the realisation.

There are some who are solid and tenacious in their vital, it is they who can be steady - others are more mercurial and easily moved by impulses, it is these who are sometimes enthusiastic, sometimes drop into fatigue. It is a matter of temperament. On the other hand the mercurial people are often capable of a quicker ardour, so that they can progress fast if they want in their own way. In any case the remedy for all that is to find one's true self above mind and vital and so not bound by temperament.
