12. Experiences of the Inner and the Cosmic Consciousness
It is a very good sign that when the thoughts and the attempt at 
disturbance come there is something that remains calm and cool – for that, like the psychic reply from within, shows that the inner consciousness is fixed or fixing itself in part of the being. This is a well recognised stage of the inner change in sadhana. Equally good is the emerging of the self-existent Ananda from within not dependent on outward things. It is a fact that this inner gladness and happiness is something peaceful and happy at once – it is not an excited movement like the vital outward pleasure, though it can be more ardent and intense. Another good result is the fading out of the feeling that “the work is mine” and the power to do it with the outward consciousness not engaging the inner being.
The sense of release as if from jail always accompanies the emergence of the psychic being or the realisation of the self above. It is therefore spoken of as a liberation, mukti. It is a release into peace, happiness, the soul’s freedom not tied down by the thousand ties and cares of the outward ignorant existence.
It was of course the Mother’s face you saw in your vision, but probably in one of her supraphysical, not her physical form and face – that is also indicated by the great light that came from the form and rendered it invisible.
