After Psychicisation and the basic psycho-spiritual transformation, the next stage in the Transformation of the being to a higher, greater, broader, and deeper spiritual state of existence is called by Sri Aurobindo "Spiritualisation". Here "Spirit" somehwat ambiguously means both what is conventionally called the "Atman", Shunyata, Buddha-Nature, and so on (hence the option for the attainment of nirvana or liberation) and the higher noetic levels of mind, which lead to transformation. As with elsewhere, I have quoted this passage at length because of the profound insight it throws on the more advanced stages and stations of the Spiritual Path. Time permitting I would like in the future to comment more on these experiences and stages
"But all this change and all this experience, though psychic and spiritual in essence and character, would still be, in its parts of life-effectuation, on the mental, vital and physical level; its dynamic spiritual outcome [Note: The psychic and the spiritual opening with their experiences and consequences can lead away from life or to a Nirvana; but they are here being considered solely as steps in a transformation of the nature.] would be a flowering of the soul in mind and life and body, but in act and form it would be circumscribed within the limitations, - however enlarged, uplifted and rarefied, - of an inferior instrumentation. It would be a reflected and modified manifestation of things whose full reality, intensity, largeness, oneness and diversity of truth and power and delight are above us, above mind and therefore above any perfection, within mind's own formula, of the foundations or superstructure of our present nature.
A highest spiritual transformation must intervene on the psychic or psycho-spiritual change; the psychic movement inward to the inner being, the Self or Divinity within us, must be completed by an opening upward to a supreme spiritual status or a higher existence. This can be done by our opening into what is above us, by an ascent of consciousness into the ranges of overmind and supramental nature in which the sense of Self and Spirit is ever unveiled and permanent and in which the self-luminous instrumentation of the Self and Spirit is not restricted or divided as in our mind-nature, life-nature, body-nature. This also the psychic change makes possible; for as it opens us to the cosmic consciousness now hidden from us by many walls of limiting individuality, so also it opens us to what is now superconscient to our normality because it is hidden from us by the strong, hard and bright lid of mind, - mind constricting, dividing and separative. The lid thins, is slit, breaks asunder or opens and disappears under the pressure of the psycho-spiritual change and the natural urge of the new spiritualised consciousness towards that of which it is an expression here. This effectuation of an aperture and its consequences may not at all take place if there is only a partial psychic emergence satisfied with the experience of the Divine Reality in the normal degrees of the spiritualised mind: but if there is any awakening to the existence of these higher supernormal levels, then an aspiration towards them may break the lid or operate a rift in it. This may happen long before the psycho-spiritual change is complete or even before it has well begun or proceeded far, because the psychic personality has become aware and has an eager concentration towards the superconscience. An early illumination from above or a rending of the upper velamen can come as an outcome of aspiration or some inner readiness, or it may even come uncalled for or not called for by any conscious part of the mind, - perhaps by a secret subliminal necessity or by an action or pressure from the higher levels, by something which is felt as the touch of the Divine Being, the touch of the Spirit, - and its results can be exceedingly powerful. But if it is brought about by a premature pressure from below, it can be attended with difficulties and dangers which are absent when the full psychic emergence precedes this first admission to the superior ranges of our spiritual evolution. The choice, however, does not always rest with our will, for the operations of the spiritual evolution in us are very various, and according to the line it has followed will be the turn taken at any critical phase by the action of the Consciousness-Force in its urge towards a higher self-manifestation and formation of our existence.
If the rift in the lid of mind is made, what happens is an opening of vision to something above us or a rising up towards it or a descent of its powers into our being. What we see by the opening of vision is an Infinity above us, an eternal Presence or an infinite Existence, an infinity of consciousness, an infinity of bliss, - a boundless Self, a boundless Light, a boundless Power, a boundless Ecstasy. It may be that for a long time all that is obtained is the occasional or frequent or constant vision of it and a longing and aspiration, but without anything further, because, although something in the mind, heart or other part of the being has opened to this experience, the lower nature as a whole is too heavy and obscure as yet for more. But there may be, instead of this first wide awareness from below or subsequently to it, an ascension of the mind to heights above: the nature of these heights we may not know or clearly discern, but some consequence of the ascent is felt; there is often too an awareness of infinite ascension and return but no record or translation of that higher state. This is because it has been superconscient to mind and therefore mind, when it rises into it, is unable at first to retain there its power of conscious discernment and defining experience. But when this power begins to awake and act, when mind becomes by degrees conscious in what was to it superconscient, then there begins a knowledge and experience of superior planes of existence. The experience is in accord with that which is brought to us by the first opening of vision: the mind rises into a higher plane of pure Self, silent, tranquil, illimitable; or it rises into regions of Light or of Felicity, or into planes where it feels an infinite Power or a divine Presence or experiences the contact of a divine Love or Beauty or the atmosphere of a wider and greater and luminous Knowledge. In the return the spiritual impression abides; but the mental record is often blurred and remains as a vague or a fragmentary memory; the lower consciousness from which the ascent took place falls back to what it was, with only the addition of an unkept or a remembered but no longer dynamic experience. In time the ascent comes to be made at will and the consciousness brings back and retains some effect or some gain of its temporary sojourn in these higher countries of the Spirit. These ascents take place for many in trance, but are perfectly possible in a concentration of the waking consciousness or, where that consciousness has become sufficiently psychic, at any unconcentrated moment by an upward attraction or affinity. But these two types of contact with the superconscient, though they can be powerfully illuminating, ecstatic or liberating, are by themselves insufficiently effective: for the full spiritual transformation more is needed, a permanent ascension from the lower into the higher consciousness and an effectual permanent descent of the higher into the lower nature.
This is the third motion, the descent which is essential for bringing the permanent ascension, an increasing inflow from above, an experience of reception and retention of the descending Spirit or its powers and elements of consciousness. This experience of descent can take place as a result of the other two movements or automatically before either has happened, through a sudden rift in the lid or a percolation, a downpour or an influx. A light descends and touches or envelops or penetrates the lower being, the mind, the life or the body; or a presence or a power or a stream of knowledge pours in waves or currents, or there is a flood of bliss or a sudden ecstasy; the contact with the superconscient has been established. For such experiences repeat themselves till they become normal, familiar and well-understood, revelatory of their contents and their significance which may have at first been involved and wrapped into secrecy by the figure of the covering experience. For a knowledge from above begins to descend, frequently, constantly, then uninterruptedly, and to manifest in the mind's quietude or silence; intuitions and inspirations, revelations born of a greater sight, a higher truth and wisdom, enter into the being, a luminous intuitive discrimination works which dispels all darkness of understanding or dazzling confusions, puts all in order; a new consciousness begins to form, the mind of a high wide self-existent thinking knowledge or an illumined or an intuitive or an overmental consciousness with new forces of thought or sight and a greater power of direct spiritual realisation which is more than thought or sight, a greater becoming in the spiritual substance of our present being; the heart and the sense become subtle, intense, large to embrace all existence, to see God, to feel and hear and touch the Eternal, to make a deeper and closer unity of self and the world in a transcendent realisation. Other decisive experiences, other changes of consciousness determine themselves which are corollaries and consequences of this fundamental change. No limit can be fixed to this revolution; for it is in its nature an invasion by the Infinite."
