The central fire is the psychic being, but it can be lit in all the parts of the being.

That the constant fire of aspiration has to be lit is true; but this fire is the psychic fire and it is lit or burns up and increases as the psychic grows within and for the psychic to grow quietude is needful. That is why we have been working for the psychic to grow in you and for the quietude also to grow and that is why we want you to wait on the Mother's working in full patience and confidence. To be always remembering the Mother and always with the equal unwavering fire within means itself a considerable progress in sadhana and it must be prepared by various means such as the experiences you have been having. Keep steadfast in confidence therefore and all that has to be done will be done.

The great fire of purification and concentration (i.e. gathering up of the consciousness and turning it fixedly towards the Divine), the psychic fire which all must pass through so as to reach the Mother permanently and completely.

It is just in the physical consciousness that it is difficult to keep the fire burning, the physical can easily follow a constant routine, but not easily maintain a constant living endeavour. Nevertheless it can be after a time be made ready to do so. All help will be given you.
