5. Planes and Parts of the Being
Fragment ID: 419
1. The spiritual consciousness is that in which we enter into the awareness of Self, the Spirit, the Divine and are able to see in all things their essential reality and the play of forces and phenomena as proceeding from that essential Reality.
2. The cosmic consciousness is that in which the limits of ego, personal mind and body disappear and one becomes aware of a cosmic vastness which is or filled by a cosmic spirit and aware also of the direct play of cosmic forces, universal mind forces, universal life forces, universal energies of Matter, universal overmind forces. But one does not become aware of all these together; the opening of the cosmic consciousness is usually progressive. It is not that the ego, the body, the personal mind disappear, but one feels them as only a small part of oneself. One begins to feel others too as part of oneself or varied repetitions of oneself, the same self modified by Nature in other bodies. Or, at the least, as living in the larger universal self which is henceforth one’s own greater reality. All things in fact begin to change their nature and appearance; one’s whole experience of the world is radically different from that of those who are shut up in their personal selves. One begins to know things by a different kind of experience, more direct, not depending on the external mind and the senses. It is not that the possibility of error disappears, for that cannot be so long as mind of any kind is one’s instrument for transcribing knowledge, but there is a new, vast and deep way of experiencing, seeing, knowing, contacting things; and the confines of knowledge can be rolled back to an almost unmeasurable degree. The thing one has to be on guard against in the cosmic consciousness is the play of a magnified ego, the vaster attacks of the hostile forces – for they too are part of the cosmic consciousness – and the attempt of the 
cosmic Illusion (Ignorance, Avidya) to prevent the growth of the soul into the cosmic Truth. These are things that one has to learn from experience; mental teaching or explanation is quite insufficient. To enter safely into the cosmic consciousness and to pass safely through it, it is necessary to have a strong central unegoistic sincerity and to have the psychic being, with its divination of truth and unfaltering orientation towards the Divine, already in front in the nature.
3. The ordinary consciousness is that in which one knows things only or mainly by the intellect, the external mind and the senses and knows forces etc. only by their outward manifestations and results and the rest by inferences from these data. There may be some play of mental intuition, deeper psychic seeing or impulsions, spiritual intimations, etc. – but in the ordinary consciousness these are incidental only and do not modify its fundamental character.
