Changes

The Self or Atman being free and superior to birth and death, the experience of the Jivatman and its unity with the Supreme or universal Self brings the sense of liberation, it is this which is necessary for the supreme spiritual deliverance: but for the transformation of the life and nature the awakening of the psychic being and its rule over the nature are indispensable.

The psychic being is organised ''around'' the divine spark. The divine spark is one, universal, the same everywhere and in everything, one and infinite, of the same kind in all. You cannot say that it is a being - it is ''the being'', if you like, but not ''a'' being. Naturally, if you go back to the origin, you may say that there is only one soul, for the origin of all souls is the same, as the origin of the whole universe is the same, as the origin of the entire creation is the same. But the psychic being is an individual, personal being with its own experience, its own development, its own growth, its own organisation; only, this organisation is the product of the action of a central divine spark.

But the day an external being (physical, mental, vital) enters into direct and constant contact with the psychic being, one may say in the same way that the ''physical'' being of this person is organised by the central divine consciousness. ...

The soul or psyche is immutable only in the sense that it contains all the possibilities of the Divine within it, but it has to evolve them and in its evolution it assumes the form of a developing psychic individual evolving in the manifestation of the individual Prakriti and taking part in the evolution. It is the spark of the Divine Fire that grows behind the mind, vital and physical by means of the psychic being until it is able to transform the Prakriti of Ignorance into a Prakriti of knowledge. This evolving psychic being is not therefore at any time all that the soul or essential psychic existence bears within it; it temporalises and individualises what is eternal in potentiality, transcendent in essence, in this projection of the spirit.
