The psychic being in the old systems was spoken of as the Purusha in the heart (the secret heart – hṛdaye guhāyām) which corresponds very well to what we define as the psychic being behind the heart centre. It was also this that went out from the body at death and persisted – which again corresponds to our teaching that it is this which goes out and returns, linking new life to former life. Also we say that the psychic is the divine portion within us – so too the Purusha in the heart is described as Ishwara of the individual nature in some places.
The word soul is very vaguely used in English – as it often refers to the whole non-physical consciousness including even the vital with all its desires and passions. That is why the word psychic being has to be used so as to distinguish this divine portion from the instrumental parts of the nature.
