5. Planes and Parts of the Being
Fragment ID: 335
The1 Jivatma, spark-soul and psychic being are three different forms of the same reality and they must not be mixed up together, as that confuses the clearness of the inner experience.
The Jivatma or spirit is self-existent above the manifested or instrumental being – it is superior to birth and death, always the same, it is the individual Self or Atman; the eternal true being of the individual.
The soul is a spark of the Divine in the heart of the living creatures of Nature. It is not seated above the manifested being; it enters into the manifestation of the self, consents to be a part 
of its natural phenomenal becoming, supports its evolution in the world of material Nature. It carries with it at first an undifferentiated power of the divine consciousness containing all possibilities which have not yet taken form but to which it is the function of evolution to give form. This spark of Divinity is there in all terrestrial living beings from the earth’s highest to its lowest creatures.
The psychic being is a spiritual personality put forward by the soul in its evolution; its growth marks the stage which the spiritual evolution of the individual has reached and its immediate possibilities for the future. It stands behind the mental, the vital, the physical nature, grows by their experiences, carries the consciousness from life to life. It is the psychic Person, caitya puruṣa. At first it is veiled by the mental, vital and physical parts, limited in its self-expression by their limitations, bound to the reactions of Nature, but, as it grows, it becomes capable of coming forward and dominating the mind, life and body. In the ordinary man it still depends on them for expression and is not able to take them up and freely use them. The life of the being is animal and human, not divine. When the psychic being can by sadhana become dominant and freely use its instruments, then the impulse towards the Divine becomes complete and the transformation of mind, vital and body, not merely their liberation becomes possible.
As the Self or Atman is free and superior to birth and death, the experience of the Jivatman and its unity with the supreme or universal Self is sufficient to bring the sense of liberation; but for the transformation of the life and nature the full awareness and awakening of our psychic being also is indispensable.
The psychic being realises at this stage its oneness with the true being, the Self, but it does not disappear or change into it; it remains as its instrument for psychic and spiritual self-expression, a divine manifestation in Nature.
The bindu seen by you above may be a symbolic way of seeing the Jivatman, the individual self as a drop of the Sea, an individual portion of the universal Divine; the aspiration on that level would naturally be for the opening of the higher consciousness so that the being may dwell there and not in the ignorance. The Jivatman is already one with the Divine in reality, but its spiritual demand may be for the rest of the consciousness also to realise it.
The aspiration of the psychic being would then translate this demand entirely for the opening of the whole lower nature, mind, vital, body to the Divine, for the love and union with the Divine, for its presence and power within the heart, for the transformation of the mind, life and body by the descent of the higher consciousness into this instrumental being and nature.
Both aspirations are necessary for the fullness of this yoga, the demand of the self on the nature from above, the psychic aspiration of the nature from below. When the psychic imposes its aspiration on the mind, vital and body, then they too aspire and this is what was felt by you as the aspiration from the level of the lower being. The aspiration felt above is that of the Jivatman for the higher consciousness with its realisation of the One to manifest in all the being. Both aspirations help and are necessary to each other. But the seeking of the lower being is at first intermittent and oppressed by the obscurity and limitations of the ordinary consciousness. It has, by sadhana, to become clear, constant, strong and enduring; it then compels realisation, makes it inevitable.
The sense of peace, purity and calm felt by you is brought about by a union or a strong contact of the lower with the higher consciousness; it cannot be permanent at first, but it can become so by an increased frequency and durability of the calm and peace and finally by the full descent of the eternal peace and calm and silence of the higher consciousness into the lower nature.
