However, you need not personally concern yourself with them so long as they remain incognito.Sri Aurobindo

The hostile forces exist and have been known to Yogic experience ever since the days of the Veda and Zoroaster in Asia (and the mysteries of Egypt and Chaldea and the Cabbala) and in Europe also from old times. These things of course cannot be felt or known so long as one lives in the ordinary mind and its ideas and perceptions – for there there are only two categories of influences recognisable, the ideas and feelings and actions of oneself and others and the play of environment and physical forces. But once one begins to get the inner view of things, it is different. One begins to experience that all is an action of forces, forces of Prakriti psychological as well as physical which play upon our nature – and these are conscious forces or are supported by a consciousness or consciousnesses behind. One is in the midst of a big universal working and it is impossible any longer to explain everything as the result of one’s own sole and independent personality. You yourself have at one time written that your crises of despair etc. came upon you as if thrown on you and worked themselves out without your being able to determine or put an end to them. That means an action of universal forces and not merely an independent action of your own personality, though it is something in your nature of which they make use. But you are not conscious, and others also, of this intervention and pressure at its source for the reason I state. Those in the Asram who have developed the inner view of things on the vital plane1 have plenty of experience of the hostile forces. However, you need not personally concern yourself with them so long as they remain incognito.
1 One may have the experiences on the mental plane without this knowledge coming – for there Mind and Idea predominate and one does not feel the play of Forces – it is only in the vital that that becomes clear. In the mind plane they manifest at most as mental suggestions and not as concrete Powers. Also if one looks at things with the Mind only (even though it be the Inner Mind), one may see the subtle play of Nature-Forces but without recognising the conscious intention which we call hostile.
