It is through the emotional being that the psychic most easily expresses, for it stands just behind it in the heart centre.

==What Is the Role of The Lower Vital Nature?==
Evidently, the condition into which you have fallen is due to an upsurging of suppressed elements in the lower vital nature. It has been compelled by the mind and the higher vital part in you to give up the little "joys and pleasures" to which it was habituated, but it—or at any rate the subconscient part of it which is often the most powerful—did that without entire conviction and probably with "reservations" and "safeguards" and in exchange for a promise of compensations, other and greater joys and pleasures to replace all it was losing. This is evident from what you write; your description of the nature of the depression, the return of what you call impure thoughts which are merely indices of the subconscient lower vital desire-complex, the doubt thrown upon the generosity of the Divine, the demand for compensation for losses, something like striking a bargain with the Divine, a quid pro quo pact, are all unmistakable. Latterly, there has been a combination of circumstances (X's turning inwards, Y's emigration etc.) which have rather suddenly increased the deprivation of its former outlets; this attack is its way of non-cooperation or protest. There is only one way to deal with it,—to cast the whole thing away—depression, demands, doubts, sex-thoughts, the whole undesirable baggage,—and have in its place the one true movement, the call for the true consciousness and the presence of the Divine. <ref>http://incarnateword.in/cwsa/31/the-lower-vital-being#p43</ref>
