Men are being constantly invaded by the hostiles and there are great numbers of men who are partly or entirely under their influence. Some are possessed by them, others (a few) are incarnations of hostile beings. At the present moment they are very active all over the earth. Of course in the outside world there is no consciousness, such as is developed in yoga, by which they can either become aware of or consciously repel the attacks – the struggle in them between the psychic and the hostile force goes on mostly behind the veil or so far as it is on the surface is not understood by the mind.
The first attempt of the possessing entity is to separate the person from his psychic, and it is that that creates the struggle. All depends on the extent and persistence of the possession – how much of the being it occupies and whether it is constant or not.
The concentration in the heart is the way to get rid of them, but there must also be a detachment of the consciousness so that it can stand back from the attack and feel separate from it.
From the higher mind upwards, all is free from the action of the hostile forces. For they all belong to the spiritual consciousness though with varying degrees of light and power and completeness.
But the great obstinate world resists my word,
And the crookedness and evil in men's hearts
Is stronger than Reason, profounder than the Pit.
And the malignancy of hostile Powers
Puts craftily back the clock of destiny
And mightier seems than the eternal Will.
