If you cannot call the Mother in what you think the right way, call her in any way – if you can’t call her, think of her with the will to be rid of these things. Don’t worry yourself with the idea whether you have true aspiration or not – the psychic being wants and that is sufficient. The rest is the Divine Grace, on which one must steadfastly rely – one’s own merit, virtue or capacity is not the thing that brings the realisation.
